who worked with manned gliders in the 1890's
Otto Lilienthal Otto Lilienthal (23 May 1848 – 10 August 1896) was a German pioneer of aviation who became known as the flying man[2]. He was the first person to make well-documented, repeated, successful flights with unpowered airplanes.[3] Newspapers and magazines published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical. On 9 August 1896, his glider stalled and he was unable to regain control. Falling from about 15 m (50 ft), he broke his neck and died the next day, 10 August 1896.
Sewing machine The first machine to combine all the disparate elements of the previous half-century of innovation into the modern sewing machine was the device built by English inventor John Fisher in 1844, thus a little earlier than the very similar machines built by Isaac Merritt Singer in 1851, and the lesser known Elias Howe, in 1845. However, due to the botched filing of Fisher's patent at the Patent Office, he did not receive due recognition for the modern sewing machine in the legal disputations of priority with Singer, and it was Singer who won the benefits of the patent.
