About Conze (from Wikipedia):
Eberhart (Edward) Julius Dietrich Conze (1904 – September 24, 1979) was an Anglo-German scholar probably best known for his pioneering translations of Buddhist texts.
Dr. Conze has been called “the foremost Western scholar of the Prajnaparamita literature.” It is especially significant that as a scholar of Buddhism he also tried to practice it, especially meditation. This was very unusual at the time he started his work, and he was regarded as eccentric in the 1940s and 1950s – objective scholars were not supposed to have any personal involvement in their subject. He was hence a forerunner of a new strain of Western scholars in Buddhism who are practicing Buddhists.
