Father and son, Victor and William Humpherson, both became dentists, albeit in different eras. Although working in different branches of dentistry, both became important members of the profession. Victor was important in the early days of NHS general dental practice, finally as chairman of the Dental Estimates Board. William was area dental officer for Croydon, heavily involved in many developments in community dental services, especially in staff education and training. He was also an organist, playing a Fantasia on three notes, specially composed for the 1980 British Dental Association's centenary meeting. Both were nicknamed 'Humph' but to avoid confusion, it is here only used to refer to William Allen.
