"BERTRAM EDWARD DUNBAR KILBURN was for over forty years the principal of Messrs. Kilburn and Strode, chartered patent agents, London, and was well known as a prominent member of that profession.
He was born in 1872 and was educated at Eastbourne College and at Trinity College, Cambridge, where he graduated B.A. in 1893, proceeding later to the degree of M.A. In the following year he was articled to the late Mr. A. J. Boult, chartered patent agent and in 1899 he became his partner. In 1906, however, he went into practice on his own account and subsequently took into partnership the late Mr. Strode. He continued to take an active part in the business until his death, which occurred on 18th July 1948.
Mr. Kilburn was elected an Associate of the Institution in 1907 and was transferred to Companionship in 1922. He was also an Associate of the Institution of Civil Engineers. He was elected to the Council of the Chartered Institute of Patent Agents in 1914, remaining an active and leading member until his death; in addition he served as President from 1921 to 1923. He was a supporter of several other societies, being a Fellow of the Royal Society of Arts, a member of the Newcomen Society, and for a number of years had served on the Council of the Society for Nautical Research. During the 1914-18 war he was attached to the Secret Patents Department of the Admiralty."
