Collection Item Summary:

Along with a number or early aircraft engines, this was included in a donation of miscellaneous wooden propellers from L.L. Walker, Sr., a member of the Early Birds of Aviation. This organization consisted of pioneer aviators that banded together for the purposes of preserving aviation history and advancing interest in aeronautics, as well as good fellowship. Membership necessitated evidence of solo flight in heavier- or lighter-than-air craft before December 17, 1916, when many pilots began training prior to entry to World War I.

Walker first flew in 1910 in a Bleriot monoplane that he built himself. It was powered by a four-cylinder Kemp engine of about 30 kw (40 hp). He was granted an Aero Club of America Aviator’s Certificate in 1915, and later founded the L.L. Walker Company of Houston, Texas, a propeller service and sales organization.
