The Dettmann name has long been associated not only with the Chatswood area but Sydney and its environs.  Beginning in 1938 when the firm was founded by Hugo Ken Conway Dettmann (known as Tim) and known as 'H.K.C Dettmann', it was successively 'Dettmann, Austin & Maclean'; 'Dettmann Maclean & Brown'; 'Dettmann & Co', 'Dettmann & Dettmann' then in 2005, Dettmann Longworth.
