Grace Rogers Cooper (November 22, 1924 – November 25, 2004) was a Smithsonian Institution curator, U.S. textile expert and vexillogist, known primarily for her seminal work Thirteen-Star Flags: Keys to Identification, published in 1973, which exposed a number of "antique" flags as modern replicas.
[1][2] Born in Sharon, Pennsylvania, she received her Bachelor of Science degree in 1946 from the University of Maryland, majoring in textiles.
Appendix VII, "A Brief History of Cotton Thread," is of particular interest to those who study antique flags.
[1] Cooper joined the North American Vexillological Association in 1979, serving as treasurer from 1980 to 1983 and president from 1983 to 1986.
The Association honored her with its Whitney Smith Award, for an outstanding contribution to North American vexillology, in 1994.
