Albin Kasper Longren's photograph album
Date: 1912-1921
This photograph album documents a number of airplanes (biplanes)designed, built and flown by Albin Kasper Longren. He built and flew Topeka's first aircraft on September 2, 1911. At two different times, Longren tried to establish an airplane factory in Topeka, Kansas. His second factory was in an abandoned woolen mill in Oakland, a neighborhood in Topeka, Kansas. The album contains photographs of the exterior and interior of this factory and numerous views of planes and plane parts. Longren's planes were well received, but his business failed because he had difficulty manufacturing numbers of planes. There are two images of a plane parked at the entrance to Gage Park in Topeka. Longren did exhibition flying at county fairs and other events in the region under the name Longren Aviators Exhibition Flyers. The album also has images of biplanes at Coffeyville, Anthony, Stockton, and other locations in Kansas as well as at least one image taken in the following states: Oklahoma, Nebraska, and Texas. Longren built a plane the was purchased by Phillip Billard, a Topeka aviator, and there are images of this plane in the album.

Albin K. Longren
Date: Between 1910 and 1915
A portrait of Albin K. Longren, who in 1911, constructed and flew his first pusher-type biplane, dubbed the Topeka I. That flight earned him the distinction of being the first to manufacture within Kansas a successfully-flown aircraft. This was the beginning of a lifelong career in aviation for Longren. As an aviator, he barnstormed throughout the Midwest, making a total of 1,372 exhibition flights from 1911 - 1914 without a major mishap. Longren channeled his income from barnstorming into his more serious interest of aircraft design and construction in his Topeka factory.

Fold-wing biplane built by Albin Kasper Longren
Date: 1921
Photograph of Albin Kasper Longren's fold-wing biplane parked in front of a garage. In less than 30 seconds, four pins could be removed and wings folded back so the plane could be stored in a Model T Ford garage. The composite fuselage was made of a hard vulcanized fiber molded to a streamline form. It weighed 550 pounds with side-by-side seating. The trial test flight took place on August 6, 1921 from Kelsey's potato field located east of the Longren factory at 1401 Winfield in northeast Topeka, Kansas.

Fuselage
Date: April 10, 1922-June 16, 1925
The patent, #1,541,976, depicts and describes Albin Longren's method of Fuselage construction circa 1922. Longren's goal was to construct an airplane body that was not only lightweight, but also durable in order to withstand the stresses related to powered flight. As illustrated in the drawing and described in the text of the patent, Longren's method of constructing a sturdier fuselage relies upon the use of ribbing along the entire length of the fuselage to provide increased rigidity and durability.
