Mary Morris Vaux Walcott (July 31, 1860 – August 22, 1940) was an American artist and naturalist known for her watercolor paintings of wildflowers.

[6] In 1887, on her first transcontinental trip via rail, she wrote an engaging travel journal of the family's four-month trek through the American West and the Canadian Rockies.

[7] Over her father's fierce objections, in 1914 Mary Vaux, then 54, married the paleontologist Charles Doolittle Walcott, a widower who was the Secretary of the Smithsonian Institution.

[8][9] In Washington, Vaux became a close friend of First Lady Lou Henry Hoover[5] and raised money to erect the Florida Avenue Meeting House, so that the first Quaker President and his wife would have a proper place to worship.

From 1927 to 1932, Mary Vaux Walcott served on the federal Board of Indian Commissioners and, driven by her chauffeur, traveled extensively throughout the American West, diligently visiting reservations.

A Kodak, if no larger instrument can be managed, yields most satisfactory results, although the better records from a larger-sized camera are an increased delight, when one has the patience and skill to obtain them.
