Loesser was the author of the books Humor in American Song and Men, Women, and Pianos: A Social History. He also wrote program notes for the Cleveland Orchestra and liner notes for recordings by Vladimir Horowitz and other musicians.
Loesser served on the faculty of the Cleveland Institute of Music beginning in 1926. From 1953 until his death in 1969, he was head of the piano department. His pupils included Sergio Calligaris and Anton Kuerti.
As a pianist, Loesser gave numerous concerts and recitals, his first during 1913 in Berlin. He often coupled his recitals with lectures which were known for their wit. He was active during the 1920s and 1930s as one half of a piano duo with the famous conductor Wilfrid Pelletier. The two made a number of recordings together that were made under the direction of Arthur Bodanzky. He also made several solo recordings, some of which have been issued on compact disc.
During World War II, from 1943, Loesser served for the US Army where he worked in the Japanese intelligence department. It was during this period that he mastered the Japanese language and after the war ended he gave recitals with lectures in Tokyo. Loesser eventually retired from the army with the rank of major.
