Benjamin B. Lipsner (September 15, 1887 – December 24, 1971)

Although employed by the Post Office Department for less than four months, Captain Benjamin Lipsner was an integral figure in the development and success of the world's first regular Air Mail Service. Born on 15 September 1887 in Chicago, Illinois, Lipsner was interested in mechanics at a young age. He attended the Armour Institute in Chicago where he received a degree in Mechanical Engineering.

In 1910 he began working as a mechanic at various automobile manufacturers, specializing in operational maintenance and procedure. At the same time he became interested in the new field of airplane mechanics, working on airplane engines in his spare time. When the United States entered World War I, Lipsner's expertise in lubrication and mechanics placed him in the Army Signal Corps, the aviation division of the United States Army. 

In 1918, Congress appropriated $100,000 to begin a regular air mail service between New York and Washington. The Army was given the responsibility of providing and maintaining the service and Lipsner was named Captain of the Air Service Production. He was in charge of the maintenance of the airplanes used in the service and was present when the first plane left from the Polo Grounds in Washington, DC on 15 May 1918.

On 10 August, the air mail service was officially transferred from the Army to the Post Office Department. A month earlier, Lipsner resigned his commission in the Army and was named First Superintendent of the world's first regular permanent civilian air mail service. The civilian service began on 12 August 1918 with Lipsner in charge of the day to day operation of the service; his tasks included creating schedules and choosing pilots and mechanics. Lipsner's organization skills kept the service, which initially operated between New York and Washington, on schedule and casualty free. 

One of the highlights of Lipsner's tenure as superintendent was the New York to Chicago pathfinding mission in September 1918. The flights were originally intended by the Air Mail Service to be a test of a new extension of the existing service. However, the test became a cross-country race between the two best pilots, Max Miller and Eddie Gardner. Although the test flights didn't immediately lead to the extension of the service, the well-publicized flights gained national attention and public support for the fledgling air mail service.

Despite the success of the service, the relationship between Lipsner and Second Assistant Postmaster General Otto Praeger began to sour. Lipsner complained that important decisions, such as the hiring of new personnel, were being made without his consent or approval. And he felt that Praeger was improperly spending money on unnecessary new planes and equipment. The conflict led Lipsner to resign from his position on 5 December 1918. His letter of resignation was critical of the Post Office Department and was printed in newspapers across the country. Praeger and Postmaster Burleson responded by claiming Lipsner had misrepresented the facts. The resignation sparked a public war of words between Lipsner and the Post Office Department.

Lipsner went on to a career in the private air industry, serving as an engineer and consultant to a number of oil companies and airlines. He became the head of Chicago's American Legion Aviation Post #651 and continued to educate and entertain people with his stories of the early days of the Pioneer Air Mail.

He appeared on a number of radio and television shows and at numerous commemorative conventions, air shows and testimonials. Despite his limited tenure during the early years of the permanent airmail service, he was remembered by many of those who knew him as the "Father of the Regular Air Mail Service." Lipsner died on 24 December 1971 at the age of 84.

Scope and Content

This collection contains material relating to the career of Captain B. Benjamin Lipsner and his involvement in the development of the first permanent air mail service. Much of the collection came to the Museum on a set of exhibition panels that Lipsner had created and displayed at various commemorative air mail functions and conferences.

Most of the material relates to the period between May and December 1918 -- the period of Lipsner's official involvement with the Air Mail service. The collection includes letters, covers, telegrams, schedules, photographs and documents. Additional material relates to Lipsner's activities later in life which also document his period of service. The bulk of the material has been grouped by the following subjects:

  • Lipsner's service in the Army Signal/Air Corps from 8 December 1917 to 15 July 1918

  • Lipsner's service as superintendent of the civilian Air Mail Service, 15 July 1918 to 6 December 1918

  • The New York to Chicago path-finding flights, 5-10 September 1918

  • The pilots that flew under Lipsner's command

  • Lipsner's life after his 6 December 1918 resignation


Milton Lipsner, son of Benjamin Lipsner, donated his father's collection to the Smithsonian's National Philatelic Collection in 1982. A list exists of the objects as they were arranged on Lipsner's original exhibit panels. Although only one panel remains, most of the removed objects correspond with the list.

In addition to the accessioned material listed below, there are over 500 accessioned and cataloged covers from Lipsner's personal aerophilately collection that are located at the National Postal Museum.

Twelve scrapbooks, photographs and miscellaneous biographical material are held by Smithsonian Institution Libraries' Postal Museum branch. Some aviation related material was transferred to the National Air and Space Museum. And a number of foreign bank notes were transferred to the National Museum of American History's National Numismatic Collection. The National Museum of American History also was given a set of stateroom keys used by Orville Wright while attending the 1937 Aeronautics Conference.

The Army Signal Corps was contracted by the Post Office Department to supply planes, pilots and mechanics for the first regular mail service between New York and Washington.

Lipsner was present that day as a Captain in the lubrication division of the Signal Corps. He took a leave of absence to work exclusively with the mail service. On 15 July 1918, the Service was turned over to the Post Office Department and Lipsner resigned his army commission to accept the civilian position of Superintendent of the Service.

On 6 August 1918, the Post Office Department announced plans for a new Chicago extension to the existing New York to Washington route. Lipsner chose his two premier pilots, Eddie Gardner and Max Miller to establish a safe route.

Miller and Gardner turned the flights into a personal competition. They left on the morning of 5 September 1918 from Belmont Park, New York. Despite numerous delays and mechanical failures, the pilots and the mail arrived safely in Chicago on 8 September. Lipsner and Assistant Postmaster General Otto Prager closely followed the flights from telegrams sent from Chicago, New York and the refueling sites in Lockhaven, Pennsylvania and Cleveland and Bryan, Ohio. Miller landed in New York on 10 September, a day after Gardner.
