meteorology

I think this is he: en.wikipedia.org/wiki/John_Park_Finley

John Park Finley (April 11, 1854 - November 24, 1943) was an American meteorologist and Army Signal Service officer who was the first person to study tornadoes intensively. He also wrote the first known book on the subject as well as many other manuals and booklets, collected vast climatological data, setup a nationwide weather observer network, started one of the first private weather enterprises, and opened an early aviation weather school.

Pretty Lady

Marion Geraldine Hogan Ingram (1919-1995) was a private meteorologist and the president of Weather Services, Inc. in Boston, Massachusetts. She appeared in several editions of Who's Who of American Women (1958/59, 1961/62 and 1964/65) - I don't have access those at the moment (nor have I been able find an obit online so far) or I would try to fill in some other details.

Marisa- This is really exciting! Thank you so much for the lead, and potential misspellings, which I'm passing along to our archivists now! We'll keep you all posted on anything else we find out about Hogan Ingram. Best, Catherine Shteynberg Smithsonian Institution Archives
