Ida Helen Ogilvie (/ˈaɪdə ˈhɛlən oʊˈgɪlvi/) (February 12, 1874 – October 13, 1963) was a United States educator and notable early twentieth century woman geologist.

[2] Columbia students attended her course at Barnard, and she was the first woman teaching Geology at the graduate level at a major university (probably beginning in 1912-1913)^.

Ogilvie was initially brought into the project by Delia West Marble, a member of the Garden Club of America, beginning their lifetime working and romantic partnership^.

[2] Ogilvie toured the country for the Land Army, attending college campuses to generate interest in the program, and directed almost 150 women at ‘Bedford Camp’, the Marble family farm in Westchester County, NY.

During World War II, she was involved with the Woman's Land Army of America to work in agriculture replacing men called up to the military.
