Michael Nicholl has retired after 45 years with the same firm.
He joined Spenser, Wilson and Co, Pellon Lane, Halifax, as an articled clerk in 1967 and rose to become a senior partner.
Since 2004 he has worked as a consultant but is now looking forward to holidays and charity work.
Mr Nicholl, of Mount Tabor, Halifax, said: “When I started there were no computers and calculating machines. The best part of the job has been getting to know and helping clients and some have become friends.”
He and his wife, Jane, have two children, five grandchildren.
