Sophia Louise Crownfield was born on March 18, 1862 in Baltimore, Maryland to parents Herman F. and Sophia H. (Ring) Crownfield. She may have received some art training while in Baltimore, because she was listed as “china painter” in a Baltimore City Directory for 1889.
Around 1889 she moved to New York City, where she undertook additional training at the Art Students League.

Crownfield began working as a designer for the textile industry, creating many floral-based patterns for the women’s dress silk trade. One consistent employer was the Cheney Silk Company of Connecticut. Crownfield patented some of her designs in the period of 1905-1916.
Crownfield died on February 10, 1929, age 67, at which time her home was 133 West 12th Street in New York.
