Bill started calling in 1955 and was a co-founder of his local callers association in 1958. He conducted caller's schools in the California's Bay Area with Kip Garvey, and called for many clubs in his time. A pioneer in the technical aspects of contemporary square dance calling, Bill attended his first CALLERLAB Convention in 1974. Since then he served on its Board of Governors, on numerous committees, and was a CALLERLAB Caller-Coach. Bill was the author of many square dance calls, books, and articles. These include The Big Five, The Top Ten, The Sight Caller's Textbook, The Extemporaneous Caller, a five-year series of articles in Square Dancing Magazine, and a syndicated square dance column, Circle Right, with his wife, Bobbie. He edited and published a national note service for callers and dancers. Bill had been heavily involved in caller training since 1974. He originated the idea of using Formation, Arrangement, Sequence, and Relationship (FASR) for describing square dance set-ups and developed a complete symbol system for depicting choreo-states. He was a pioneer in sight calling and resolution techniques. He presented a paper entitled "Introduction to Sight Calling" in 1966 and introduced the idea of square dance states in 1972 in a book entitled "Symmetric Choreography and Sight Calling." Bill had a stroke which affected his ability to produce speech, and died of complications due to pneumonia on 1/28/2009.
