Volunteered in the library at the RES when it was based in Queens Gate making weekly visits from Bromley, Kent, at his own expense. We met there on many occasions when I was acting librarian and he was always very helpful. After I left he continued to supply me with photocopies of many unique items he'd found routing around in the basement. His impressive knowledge of historical and bibliographic matters concerning the coleoptera was unrivaled, supported by an extensive library of his own packed closely onto double-banked shelves at his home in Kent.
