About Joseph Tilly
- Joseph Marie de Tilly (16 August 1837 – 4 August 1906) was a Belgian military man and mathematician. He was born in Ypres, Belgium.
- In 1858, he became a teacher in mathematics at the regimental school.
- He began with studying geometry, particularly Euclid's fifth postulate and non-Euclidean geometry.
- He found similar results as Lobachevsky in 1860, but the Russian mathematician was already dead at that time.
- Tilly is more known for his work on non-Euclidean mechanics, as he was the one who invented it.
- He worked thus alone on this topic until a French mathematician, Jules Hoüel, showed interest in that field.
- Tilly also wrote on military science and history of mathematics.
- He died in München, Germany.
