Karen L. Cohen was a high school math teacher before getting her Masters of Science degree in Computer Science. Most of her computer career was at AT&T Bell Labs, where she was in the forefront of data communication network development and was awarded a patent on one of her inventions in 1985. It is at Bell Labs that she learned technical writing.
In the mid-1970s Cohen started working in metals and enameling because she had loved them as a teen at summer camp. In 2002 she published her first book on enameling. In the same year, she started the enameling program at a summer art camp for kids where she taught for 15 years, and eventually coordinated their three jewelry studios—enameling, metals, and beading. In 2019 she published her completely rewritten second book on enameling, The Art of Fine Enameling, Second Edition, which was double the size of the first edition.
Today Cohen is retired from computing, but still teaches enameling and beading in various venues to both adults and children. She is a Studio Button Artist, but also continues to create dolls, wall pieces, jewelry, and more. In writing this book, Cohen extensively researched buttons, Japanese enameling, and old enameling techniques and is amazed at what she was able to uncover about the connection to buttons currently available for collectors.
