At four foot eight (4'8") and less than a hundred pounds she seemed an unlikely candidate to be able to meet and to succeed at the very physical demands placed on a sculptor, but the teacher, Lorado Taft decided to give her a chance and they were to remain friends and co-workers for the rest of their lives.
"[1] When Taft died in 1936, leaving much of the Heald Square Monument – a sculpture group of George Washington, Robert Morris and Haym Salomon – undone, she was one of several sculptors who were commissioned to finish the piece (1941).
In 1902, reclusive Colorado Springs millionaire W. S. Stratton died and someone there realized that Walker was in town and asked her to make a death mask, which she did.
The family was so impressed with Walker that they commissioned her to do a bust, followed by a large carved granite cemetery marker and finally an over-life-sized statue of Stratton.
[5] Lorado Taft, in his groundbreaking The History of American Sculpture mentions Walker as a significant young sculptor and specifically refers to her Chief Keokuk statue.
