at Kinloch for a few days before returning east. The remainder of the 1911 season was spent flying exhibitions at various eastern points.

Through 1912-1914 Walden continued his flying school, built more planes through the Model IX and kept up his flying practice. In addition, students Fitzsimmons, Olsen, and Ceretti did some flying for him. In 1915 Walden did some research work on a radio-controlled missile which he called "the Walden Aerial Projectile." In May, 1917, he organized the Walden-Hinners Company, with offices and factory at Edgewater, New Jersey. The firm was organized to take on government aircraft projects, and wings and surfaces were made through World War I. 

From 1926 through 1932 he was founder and president of the Walden Aircraft Corporation, Long Island City, Long Island, formed to work on various aeronautical research projects. There he made some valuable fundamental research discoveries related to increasing the lift of modern multimotored wings by proper direction of the propeller slipstream. For some time his findings on this have had universal acceptance in aerodynamic planning of modern aircraft. Waldem also developed means of insuring greater accuracy in dive bombing practice. During his lifetime some fifty patents of a widely ranging variety were granted him. 

Dr. Walden Maintained a dental office for many years, where he occasionally continued his practice for lifelong friends and old patients. Combined with this office was a small workshop and laboratory where he personally carried out private research on various projects of interest to him. Dr. Walden passed away in New York on September 13, 1964, survived by his wife, three sons and nine grandchildren

 Early Bird and Flying Pioneer Henry Walden certainly contributed a very major part of early American aviation history. His foresight in pioneering the monoplane exemplifies his sound creative judgement. He was also a member of the Quiet Birdmen and contributed many articles on aviation to various magazines. His was life of hard work, sacrifice and a firm determination to carry on in
