Otto Lilienthal fue un ingeniero industrial y aeronáutico alemán. Fue uno de los pioneros del vuelo y su estudio, después de un acercamiento experimental anterior establecido en el siglo XVIII por sir George Cayley. Las fotografías en las que aparece volando en el aire fueron publicadas internacionalmente e influyeron en la opinión pública y científica sobre la posibilidad de que una máquina voladora llegase a ser una realidad plausible después de un tiempo de fantasía ociosa y poco desarrollo científico.

Experimentó, a menudo acompañado por su novia y por su hermano Gustav, con planeadores que evolucionaban de acuerdo a los movimientos del cuerpo del piloto y que hacía volar lanzándose desde una colina campestre que él construyó cerca de Berlín y también desde colinas naturales, especialmente en la región de «Rhinower Berge» . Sus primeros diseños fueron planeadores monoplanos, diseñando y construyendo más tarde naves con otras configuraciones, como biplanos, naves con alas en tándem, con alas batientes y con alas plegables.

Lilienthal hizo investigaciones básicas en la descripción exacta del vuelo de los pájaros, especialmente de cigüeñas, y usó diagramas polares para describir la aerodinámica de sus alas. Ayudó a probar que el vuelo más pesado que el aire era práctico sin las alas de aleteo, poniendo la base para que Alberto Santos Dumont construyese con éxito algunos años después el primer avión, despegando sin auxilio externo. Fruto de sus estudios y sus más de dos mil vuelos, realizó varias publicaciones, siendo la más conocida una obra denominada El vuelo de los pájaros como base de la aviación, publicada en 1889 y traducida al inglés en 1911.

Además de dedicar su vida a la investigación sobre el vuelo, Lilienthal fue también inventor, ideando un motor pequeño que funcionó con un sistema de calderas tubulares. Su motor era más seguro que otros motores de la época. Este invento le dio la libertad económica para dejar su trabajo y centrarse en la aviación. Su hermano Gustav vivía en Australia en ese momento, y Otto no participó en ningún experimento de aviación hasta la vuelta de su hermano en 1886.

Fundó una compañía de calderas y máquinas de vapor y obtuvo veinticinco patentes, una de ellas para una máquina usada en la minería y cuatro relacionadas con la aeronáutica.

La contribución más grande de Lilienthal fue el desarrollo del vuelo más pesado que el aire. Trabajando conjuntamente con su hermano Gustav, realizó más de 2000 vuelos en planeadores de su diseño, comenzando en 1891 con su primera versión del planeador, el Derwitzer, hasta su muerte en un accidente de aviación en 1896. Lilienthal sufrió un gran número de colisiones en sus experimentos, por más que su planeador sólo podía alcanzar velocidades y altitudes bajas.

El 9 de agosto de 1896, sufrió un grave accidente, precipitándose desde 17 metros de altura, rompiéndose la columna vertebral. Falleció al día siguiente en una clínica de Berlín, siendo sus últimas palabras "Opfer müssen gebracht werden!" .

Frases Otto Lilienthal

„I, too, have made it a lifelong task of mine to add a cultural element to my work, which should result in uniting countries and reconciling their people.“

—  Otto Lilienthal
Context: I, too, have made it a lifelong task of mine to add a cultural element to my work, which should result in uniting countries and reconciling their people. Our experience of today's civilisation suffers from the fact that it only happens on the surface of the earth. We have invented barricades between our countries, custom regulations and constraints and complicated traffic laws and these are only possible because we are not in control of the 'kingdom of the air', and not as 'free as a bird'. Numerous technicians in every state are doing their utmost to achieve the dream of free, unlimited flight and it is precisely here where changes can be made which would have a radical effect on our whole way of life. The borders between countries would lose their significance, because they could not be closed off from each other. Linguistic differences would disappear, as human mobility increased. National defence would cease to devour the best resources of nations as it would become impossible in itself. And the necessity of resolving disagreements among nations in some other way than by bloody battles would, in its turn, lead us to eternal peace. We are getting closer to this goal. When we will reach it, I do not know. Letter to Moritz von Egidy (c. January 1894) - Original German text online http://www.lilienthal-museum.de/olma/l1852.htm

„Artificial flight may be defined as that form of aviation in which a man flies at will in any direction by means of an apparatus attached to his body, the use of which requires personal skill.“

—  Otto Lilienthal
Context: Artificial flight may be defined as that form of aviation in which a man flies at will in any direction by means of an apparatus attached to his body, the use of which requires personal skill. Artificial flight by a single individual is the proper beginning for all species of artificial flight, as the necessary conditions can most easily be fulfilled when man flies individually. Variant translation: Artificial flight may be defined as that form of aviation in which a man flies at will in any direction, by means of an apparatus attached to his body, the use of which requires the dexterity of the user.

„All flight is based upon producing air pressure, all flight energy consists in overcoming air pressure.“

„To design a flying machine is nothing. To build one is something. But to fly is everything.“
