In Leipzig Osthoff had adopted Neogrammarian ideas from Leskienand soon became one of the main proponents of this school. His main scholarly work dealt with phonology and morphology of Greek and Latinand their IE background. He taught regularly Sanskrit. He reconstructed the syllabic r for IE “Ursprache”. He was very careful with details and tried to include every possible aspect of the problem discussed. He was close friend of Brugmann. In field he studied Armenian (from Mechitarists in Venice 1882 and 1883), Welsh (in North Wales 1905) and Irish (in Aran Mor 1907). Among his students were Güntert, B. I. Wheeler and J. Wright.
