In the previous two installments on inventor Benjamin Miessner, we explored his process for inventing, and the life-long feud that his inventing brought upon him. Before Miessner could invent anything, however, he needed to learn the tools of the trade. Towards this end, Miessner joined the United States Navy (hereafter referred to as the Navy), to take advantage of its free schooling and valuable experience opportunities, while saving up to attend engineering school at Purdue University. Photographs, letters home, and logs in the Benjamin F. Miessner papers provide a glimpse into the life of a wireless operator in the Navy during the early 20th century, and Miessner’s journey towards becoming an accomplished inventor. They also provide a fascinating glimpse into the experiences of an American traveling around Europe just prior to the outbreak of the 1st World War.

Miessner discusses the importance of completing his education with the Navy, May 27, 1908

In 1908, Miessner left smalltown Indiana for the big city. Arriving at the Navy Electrical School in Brooklyn, New York in May, he began the 21-week program to become a wireless operator. For Miessner, joining the military wasn’t about patriotism, though he didn’t lack an appreciation for his country, but rather for the skills that this education could afford him. In a letter home to his father, Miessner discussed being able to avoid paying the discharge fee of $100 by simply not taking the examination at the end of his 21 weeks of school, should he “[get] tired of the service.” He was quick to dismiss the idea, however, stating he wanted “to get a thorough knowledge of the trade and not quit before I’m half through.”

No further correspondence with his family from 1908 survives in the collection, but several clippings from the Navy and Army Register provide a little more insight into the type of education Miessner received at the electrical school, including both images of the classroom as well as hands-on training. Miessner himself appears in the first classroom scene.

Come 1909, Miessner had completed his education and begun work as a wireless radio operator. By this time, he was stationed at the Navy Wireless Station in Washington, D.C., where he helped the Navy test new wireless apparatuses submitted by outside contractors for evaluation. This work allowed Miessner to network with big names in the industry, including Dr. Fritz Lowenstein, whom he would later work for. Two such individuals who figure in Miessner’s letters are Dr. Louis Austin, Inspector of Wireless Telegraphy for the Navy, and George Clark, Sub-Inspector. George Clark in particular is mentioned by Miessner as a mentor of sorts, who showed him how to conduct their tests. In his letter of November 9th, Miessner tells of learning “how to measure heights with transit,” and having measured the height of their aerial at 182 feet.

Miessner’s main duty during this time, however, was listening for and sending wireless telegraphs, as several photographs and negatives attest. In a letter to his older brother, Albert, Miessner discusses testing how far the signal from their wireless set could reach. Daily messages were exchanged with Key West, Florida, located some 1,000 miles south of Miessner’s D.C. location. San Juan, Cuba, located 1,345 miles south of his position, reportedly received his signal as well, but their return signal was not caught by Miessner. The cold, November weather and clearer morning conditions had aided in their endeavors, according to Miessner.

Working the wireless set also gave Miessner chances to brush up against “royalty.” In his November 1909 letter to Albert, Miessner mentions that the Mayflower was docked just outside his wireless station, and would be leaving that evening for Norfolk. Among its passengers would be President William Taft and First Lady Helen “Nellie” Taft, as well as Andrew Carnegie and his wife, whom Miessner expected to “get a good squint at” as they boarded the ship. Another mention of royalty comes in the form of Miessner’s scratch paper, circa 1910, which is the only example in the collection of the types of messages received by Miessner in his work. It consists of international news, including the announcement of the marriage of Prince Victor Boneparte of France to the Belgian Princess Clementine in Moncalieri, Italy.

1910 makes up the bulk of the Navy-related correspondence sent home, while also providing more insight into his activities outside of the Navy. By this time Miessner was stationed aboard the U.S.S. South Carolina, as part of the Atlantic Fleet, where he would remain until leaving the military in 1911. In November 1910, the Atlantic Fleet set sail for a tour of Europe, with the South Carolina making stops at Cherbourg in France and Portland in England. In his letters home, Miessner provides details on the fleet, including its size and the ships that made it up, the formation they traveled in, and the route they took. He also provides a detailed glimpse into the experience of traveling across the Atlantic by boat – waves twenty to thirty feet high, crashing onto the deck; utensils flying about while trying to eat; and sailor jostling into each other and trying to avoid meeting the floor face first. “Lots of fun,” Miessner noted to his father.

Miessner also discusses receiving wireless signals from land while out in the ocean, containing the day’s news – likely making mention of the scratch paper found in the same folder as the letter. According to Miessner, the cat-whisker detector he created was primarily responsible for the South Carolina being able to receive the signals. This type of detector, developed several years earlier for use on land, was not suitable for use on battleships, owing to the vibration of the ship’s engine and shock of gunfire making contact from the detector unreliable. Miessner’s detector used a spring-loaded contact, thus making it more reliable, to the point that it was later made standard equipment on all Navy installations. Photographs taken by Miessner show off his detector, as well as how it was hooked up to the South Carolina’s receiver.

After his initial letter, Miessner’s focus turns toward his explorations of Portland and Cherbourg, as well as short trips made to London and Paris during shore leave. Miessner offers an American’s perception of 1910 England and France, describing their transportation system, infrastructure, hotel accommodations, and culinary arts. He also provides cost comparisons for purchases in francs, pounds, and dollars, giving insight to the price of goods in that time, and the exchange rate for multiple currencies. In a more interesting story, Miessner tells of an incident involving a fellow sailor getting hit by a car in the streets of Paris, and gives details on the ensuing legal suit and settlement.

When contrasting the past with the present, Miessner also shows how similar the interests of a tourist from 1910 were to one in 2024. Spots he visited included the Eiffel Tower, Tomb of Napoleon, British Museum, Westminster Abbey, Winsor Castle, and Buckingham Palace. While his Paris trip followed his own itinerary, in London he made use of the services of a tourist agency, which provided the same types of guided tour that are still around today.

Miessner confesses to his father that his trip to Europe, while enjoyable, might not be the best for the welfare of his inventions, December 25, 1910

While Miessner enjoyed traveling around Europe and wished they “were going around the world,” his letters home also provide a reminder that his job in the Navy was never a priority for him over his dream of being an inventor. “I’m afraid this going away will not be the best thing for the welfare of my inventions,” Miessner wrote to his father from Weymouth, England. He also joked about “collecting testimonials” from all of the wireless operators who made use of his detector.

Miessner recounts to his father the loss of a torpedo, April 21, 1911

1911 opens with the Atlantic Fleet leaving Europe for Cuba, but this trip only gets a passing mention by Miessner in some 1910 letters home: “we stay [in England] three weeks, then for about three months of target practice drills, and tactical maneuvers at Guantanamo, Cuba.”[1]  By April, Miessner had returned Stateside, with the South Carolina traveling up and down the New England coast, and performing speed and firing trials. In one humorous letter, Miessner tells of them losing a torpedo while training with it. The sailors spent the day diving and searching for it, only for it to show up the next morning floating some 300 yards from the ship. An attempt was made to recover it, but 75 mile per hour gales accompanied by snow and rain made the conditions at sea too rough, and the torpedo had vanished once again by the time weather conditions improved. Roughly $7,000 ($224,854 adjusted for inflation) down the toilet, by Miessner’s estimation.

The same April 1911 letter again stressed Miessner’s concern for his inventing business. He expected to be in New York a week after writing, and was planning to meet with “the Wireless Company” to discuss selling his detector. At the time he felt the financial success of his invention seemed slim, although his book “On the Early History of Radio Guidance” reveals that he ultimately succeeded in selling the patent to John Firth of the Wireless Specialty Company for $200 (about $6,500 adjusted for inflation).

The last item in Miessner’s papers related to his first tour with the Navy comes in the form of a two-page log. It briefly recaps the Atlantic Fleet’s second tour of Europe, May-July 1911, including stops in Denmark, Sweden, Russia, and Germany. No details of Miessner’s escapades in those countries are included, noting only that the visits had been “of great interest and enjoyment,” but that he was glad to be back in the U.S. A brief mention of life in the Navy is included, as the warmer weather in Cape Cod Bay compared to the Baltic Sea had allowed the sailors to switch from their blue uniforms to the “much cooler white uniforms.”

Miessner was honorably discharged from the Navy on July 27, 1911 in Provincetown, Massachusetts. After a brief stint working for John Hays Hammond, Jr. and Dr. Fritz Lowenstein, 1911-1912, Miessner achieved his goal of studying electrical engineering at Purdue University. Following his departure from Purdue, Miessner returned for a second tour in the Navy, 1916-1918, as Expert Radio Aid for Aviation. This time around, Miessner had already acquired both the education and practical experience he needed to be an inventor, so his involvement here was strictly professional in nature. His primary contribution during this period was the development of radio for communication on aircraft, including devices to mitigate the noise interference encountered, which at this time was not available in the U.S. as it was in Europe, where World War 1 was already raging. Photographs, correspondence, and notebooks in Miessner’s papers document his second tour in great detail.

[1] According to the Naval History and Heritage Command, the South Carolina returned to Norfolk for repairs in January 1911, not making it to Cuba until January 1912. This may explain why Cuba does not feature again in Miessner’s letters after its first mention. (https://www.history.navy.mil/research/histories/ship-histories/danfs/s/south-carolina-iv.html#).

In the last installment on the Benjamin F. Miessner papers, we explored the life cycle of an invention, from conception to testing, patenting, and sale. We also touched on the legal troubles that an inventor could find themselves embroiled in, both as the prosecutor and the defendant in infringement suits. The legal suits discussed last time were professional in nature and not highly publicized, as was the case with most of Miessner’s court cases. This was not always true, however, as Miessner also had a deeply personal feud with a fellow inventor, John Hays Hammond, Jr., which led to repeated legal action and public debate.

From 1911-1912, Miessner was in the employ of John Hays Hammond, Jr., with whom he worked on the development of wireless radio-controlled torpedoes for submarines – a study Miessner referred to as “radiodynamics.” Although the two men got along well at the start, they parted on bitter terms, with Miessner accusing Hammond of denying him credit for his inventions, which Hammond had been patenting in his own name, as well as reneging on a promise to finance Miessner’s college education.

While attending Purdue University after leaving Hammond’s employ, 1913-1916, Miessner was involved in a series of legal and personal battles with Hammond. In 1913, Hammond sought to obtain a written promise from Miessner that he would not patent or disclose any of the ideas he had developed while working for Hammond; a request which Miessner refused. Going a step further, Miessner gave several lectures on devices he developed with Hammond throughout 1913, and published an article in the Purdue Engineering Review on Hammond’s radio-controlled torpedoes in 1915.

Letter from Flexner on blocking the sale of Hammond’s torpedo patents

During this same period (1913-1916), Hammond sought to sell the patents he made from his and Miessner’s work to the United States (U.S.) Government, which Miessner among others sought to block legally. Miessner, tied up with schoolwork and lacking financial means, utilized Simon Flexner, the uncle of one of his fraternity brothers and head of the Rockefeller Foundation for Medical Research, to hamper Hammond’s efforts. This was ultimately futile for Miessner, as Hammond had immured his patents in the archives of the Patent Office, where they were immune to interference proceedings.

From about 1914 to 1919, Hammond attempted on multiple occasions to acquire Miessner’s notebooks from his time working under Hammond; either for use in his negotiations with the U.S. government, and/or to prevent Miessner from using them against him. After some cordial requests, Hammond became increasingly frustrated with Miessner’s lack of cooperation, threatening legal action if Miessner did not comply. Miessner, for his part, ignored or outright refused all of Hammond’s requests, holding his notebooks close to his chest.

Miessner’s laboratory notebooks from his employment under Hammond

In 1915, Miessner attempted to publish a book, “Radiodynamics, the wireless control of torpedoes and other mechanisms,” detailing among other things his work with Hammond on radio-controlled torpedoes. Although Hammond initially gave permission to describe work Miessner completed for him, he later interfered with the book, threatening both the publishers and Miessner with legal action should they make his private work public. After being permitted to review a draft for the book, Hammond let up on his efforts to prevent publication, but again threatened legal action if any of his more recent work were to make its way into the book. This interference delayed publication until 1916.

Letter to Brigadier General E.M. Weaver regarding Hammond’s interference in the publication of “Radiodynamics”

After several rounds of threatened legal action, Miessner and Hammond first came to actual legal blows, albeit indirectly, throughout the mid-1920s, when the Radio Corporation of American (RCA) sued the George Walker Company for patent infringement. Although various patents were used by RCA in the suit to support their claims, two of them belonged to Hammond Jr., who was a director of RCA at the time. This decision brought Miessner into the case, leading him to testify in 1927 on behalf of the George Walker Company, where he asserted that he was the true inventor of the claims in Hammond’s patents, and Hammond had appropriated his work. By August 1927, RCA had dropped the Hammond patents from the suit, and the case as a whole was dropped in June 1929. Although Hammond never took part personally in the case, he did have two men, Edward H. Loftin and E.S. Purington, offer affidavits disputing Miessner’s testimonies in the George Walker case and an earlier case between RCA and Splitdorf. Interestingly, these affidavits weren’t made until 1938, 11 years after Miessner’s 1927 testimonies in the above cases. Even more interesting, Loftin had been Miessner’s patent lawyer from 1925-1930, and had represented Miessner in both cases!

In 1939, Miessner and Hammond Jr. were again entangled in a legal dispute, when Hammond brought charges against several electronic piano companies utilizing Miessner’s patents, for infringing upon his own patents. Unlike the previous instance, a suit was not levied against the companies, with many of the companies choosing instead to enter formal discussions with the lawyers for both inventors. Miessner’s papers do not provide insight into how this case ultimately ended, although it indicates that several of the companies chose to license Hammond’s patents in addition to Miessner’s, in order to avoid a potentially more costly legal suit. Other companies seemed more inclined to believe that Hammond patents weren’t relevant to their products, although it’s unclear if they ultimately yielded to Hammond’s demands.

Letter from Lee de Forest on Hammond’s article and Miessner’s rebuttal

The final dispute between Miessner and Hammond took place between 1957 and 1964. It was initiated when Hammond, along with the previously mentioned E.S. Purington, published an article in the September 1957 Proceedings of the IRE (Institute for Radio Engineers), in which they patted themselves on the back for their “pioneering” role in the development of modern radio-electronic technology. This upset a number of inventors, who were quick to respond. Lloyd Espenschied, a member of IRE’s History Committee and friend of Miessner’s, wrote a lengthy critique of the paper’s claims in December of 1957, to be published in the IRE’s proceedings in July 1959. This led to a series of back-and-forth articles between the duo of Hammond and Purington and Espenschied, continuing until 1962. Lee de Forest, a prominent inventor in the same field as Miessner and Hammond, chose not to write a formal response, but in a letter to Miessner described the Hammond-Purington article as “evidently grotesque and arrogantly conceited,” and hoped “Hammond’s grotesque designs and claims be torn to tatters by the letters of Espenschied and yourself.”

Miessner’s original 110-page rebuttal to Hammond’s IRE article

For his part, Miessner wrote a 110-page rebuttal to the Hammond-Purington article in January 1958, but found that its length prevented the IRE from accepting it for their proceedings. After some discussions with members of the IRE, including Lloyd Espenschied and fellow IRE History Committee member Haraden Pratt, Miessner chose to drop the subject, as he did not wish to edit the manuscript down to a length befitting the IRE’s proceedings. The matter then lay dormant until 1962, when the IRE awarded Hammond its Medal of Honor, reigniting Miessner’s indignation. In response, Miessner once again dug up his 1958 rebuttal and tried to have the IRE (during this time merged with the American Institute of Electrical Engineers to form the Institute of Electrical and Electronics Engineers, IEEE) publish it. Espenschied and Pratt both maintained their stances on its ineligibility for the proceedings, but suggested it might suit a book format.

Miessner’s book “On the Early History of Radio Guidance,” published in 1964

Towards this end, Miessner partnered with Dr. Charles Süsskind of the University of California, Berkley, who recommended Miessner to a publisher, and agreed to work as his editor. The pair worked together throughout 1963, with Süsskind rearranging Miessner’s 1958 manuscript to be chronological and trimming the fat from it, while Miessner provided references and additional information to clarify certain points and place emphasis on the aspects of his original manuscript that he felt were most important. The resulting book, “On the Early History of Radio Guidance,” was published in 1964, with complimentary copies sent to all 1,112 U.S. members of the IEEE, at Miessner’s expense. It received a minor rebuttal from Hammond, in the form of a 1964 reprinting of “The History of the Intermediate Frequency,” consisting primarily of Loftin and Purington’s 1938 affidavits against Miessner.

This marked the end of the pair’s long-running rivalry, as Hammond passed away on February 12, 1965, before any further debate between the two men could commence. It was Miessner’s desire that a historian would one day review the record and set straight, once and for all, who was responsible for the developments of the radio and electronics fields. To date, it is believed that this work has not yet been undertaken. Perhaps someone amongst you, dear readers, might be able to give this rivalry the conclusion Miessner desired?

Miessner may never have met Hammond, nor gained the skills to become an inventor, had he not decided to join the United States Navy right out of high school. It was through the Navy that he gained his first formal education in electricity, and brushed shoulders with engineers and inventors who would have a great impact on Miessner and his trajectory in life. Tune in next week for the final installment in this three-part spotlight on the Benjamin F. Miessner papers, where we will explore Miessner’s formative years in the Navy.
