Biography
Hohmann was born in Hardheim, the son of a doctor. Whilst a boy, he lived with his family in Port Elizabeth, South Africa for a time, before returning to Germany. He studied civil engineering at the Technical University of Munich, graduating in 1904. He then worked for the municipal councils of Vienna, Hanover and Breslau before settling in Essen, where he eventually held the post of chief architect.
Between 1911 and 1915, Hohmann became interested the problem of interplanetary spaceflight. He later realised that minimising the amount of fuel that the spacecraft had to carry would be an important consideration, and plotted a variety of orbits until he found the one that now bears his name. He published his findings in Die Erreichbarkeit der Himmelskörper (The Attainability of the Celestial Bodies). He was influenced in part by the German science fiction author Kurd Laßwitz and his book Two Planets.
The importance of this work saw Hohmann become a leading figure in Germany's amateur rocketry movement in the late 1920s, the Verein für Raumschiffahrt (VfR - "Spaceflight Society"). Following the rise to power of the Nazi party, Hohmann distanced himself as much as possible from rocketry, wishing to play no part in the development of the rocket as a weapon.
He died in an Essen hospital shortly before the end of World War II as a result of stress experienced during the intense Allied bombing of the city.

Famous quotes containing the word biography:
“A great biography should, like the close of a great drama, leave behind it a feeling of serenity. We collect into a small bunch the flowers, the few flowers, which brought sweetness into a life, and present it as an offering to an accomplished destiny. It is the dying refrain of a completed song, the final verse of a finished poem.”
—André Maurois (1885–1967)
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
—Henry David Thoreau (1817–1862)
“The death of Irving, which at any other time would have attracted universal attention, having occurred while these things were transpiring, went almost unobserved. I shall have to read of it in the biography of authors.”
—Henry David Thoreau (1817–1862)
