In 1943, Lutterlough applied for a job at the Smithsonian
National Museum of Natural History (NMNH). - and held that position for 14 years, during which she studied the museum's exhibits on her lunch break and became "a one-women [sic] information bureau" to museum visitors. Lutterlough started on that path in 1957, when she asked an insect curator, J.F. Gates Clark, if she could work in his department, and gained a position as insect preparator.
Jeannine Smith Clark worked at the NMNH as a volunteer tour guide from the late 1960s, and
Margaret Collins, an African-American zoology professor at
Howard University, was a research associate at the NMNH from the late 1970s. There were no other African-Americans employed as scientists there in 1985. African-Americans were still greatly under-represented among entomologists in 2008, when only eight faculty members of 1,348 on U.S. websites could be identified as African-American. Lutterlough worked on identifying the NMNH's insect collection, becoming a research assistant within two years. Lutterlough took college courses in science and writing, and studied German to support her development as an entomologist. Among her achievements were restoring 35,000 ticks, enabling her and her supervisor, Dr. Ralph Crabill, to identify 40
type specimens (a specimen that is the reference point for others in its species). She retired from NMNH after 40 years. ==Personal life==
