[7] Outside of her work on isopods, Richardson was the President of the Vassar College Club of Washington, D.C. from 1911–1912 and she was a charter member of the Captain Molly Pitcher Chapter, Daughters of the American Revolution, going on to be a Historian, Treasurer, Vice-Regent, and then Regent from 1914–1915.

This work covered all terrestrial, freshwater, and marine isopods in North America with keys, references, and descriptions.

[2] She wrote reports in foreign publications, including materials from the National Museum of Natural History, Paris and the Rothschild collections from East Africa.

Over the course of her career Richardson described over 70 new genera and nearly 300 new species of isopods and tanaids, many of which she named after colleagues or those who gifted collections to her.

[2] In turn the isopod species Caecidotea richardsonae and harpacticoida copepod genus Harrietella, among many others, are named after her.
