Otto Lilienthal

Lilienthal wingflap experiment

The first glider equipped for man

Lilienthal in mid-flight, c. 1895

Otto Lilienthal, properly Karl Wilhelm Otto Lilienthal, born 23 May 1848 in Anklam, deceased 10 August 1896 in Berlin, was a Prussian aeronaut known for his pioneering work on gliders.

He seems also to have worked with wings, of the flapping variety.

He filed many patents, beyond the field of aeronautics, mainly about steam engines.

Buyers of Lilienthal gliders

From Schwipps (1988), p123), via German wikipedia:

• Nine purchasers of the normal sewing machine are known by name (buyer, delivery date):

• Heinrich Seiler, 1894,
• Charles de Lambert , summer 1894,
• Alois Wolfmüller, December 1894,
• Kilian Frank, February, 1895,
• TJ Bennett, March 1895,
• George Francis Fitzgerald, March 1895,
• Charles El Brown, late spring 1895,
• Nikolai Yegorovich Zhukovsky, October 1895,
• William Randolph Hearst, April 1896.
• American aviation pioneer Octave Chanute also asked for an apparatus in the spring of 1895. There was no sale.
• In 1896 the US aviation sponsor James Means planned the delivery of several gliders with pilot training in Berlin, which did not come after Lilienthal's deadly crash.
