Obituary: MNRAS 89, 312 (1931); PASP 40, 413 (1928)
Together with Stone, Muller and Parrish, Leavenworth observed nebulae with the new 26¼" refractor (f/14.9), made by Alvan Clark & Sons (installed in 1885; see picture). He discovered 250 NGC- and 3 IC-objects. 243 are "real", 3 are stars or star groups, 10 are "not found" and IC 1308 is a HII region (Hubble X) in Barnard's galaxy NGC 6822.

Stone is mentiond by Dreyer as "observer"
for the following objects. But they were found by others due to identities.
NGC 563 was found twice by Leavenworth. The objetcs found by Swift in 1886
might be discovered nearly parallel. Opposite to Swift, Leavenworth gives
no exact discovery date. It is not clear who found NGC 3502 = NGC 3479 first,
Leavenworth or Stone.
