Betty Williams, a theatrical costumer in New York City, pioneered research on commercial patterns in the early 1980s. She became a leader in the field, establishing a major personal pattern collection and encouraging others to actively participate in the collection and storage of patterns. Betty passed away in 1997 leaving a wealthy legacy of research, and an extensive pattern collection now housed at the University of Rhode Island. The Williams Collection is combined with the URI and Joy Spanabel Emery Collections in the Commercial Pattern Archive in URI Library Special Collections.
