Alfred von Glenn
Russian cellist (b. 1858; d. 1927), born as Konstantin Edmundovich von Glen (Константин Эдмундович фон Глен); later known as Alfred von Glenn.
A student of Karl Davydov at the Saint Petersburg Conservatory, Glenn gave solo cello recitals in cities such as Dresden, Vienna, Paris and London, and regularly performed with Sergey Taneyev, Aleksandr Ziloti, Vasily Safonov, Leopold Auer and Jan Hřímalý.
From 1880 to 1890 he was principal of the cello, double bass and chamber ensemble classes at the Kharkov Music School, and in 1888 he founded the student symphony orchestra at the city's university. At the invitation of Vasily Safonov, in 1890 he became professor at the Moscow Conservatory (where his students included Gregor Pyatigorsky), and taught there until his retirement in 1921.
