The Society of Engineers' chief executive, Ian Chisholm, has died aged 67.
The SOE said Chisholm, who joined the society in 2001, left an 'incredible legacy' behind him.
Ian was appointed chief executive of SOE last year, and the organisation said he played an instrumental role in making it an "influential, thriving" society.
SOE president Howard Seymour said: “Ian leaves an incredible legacy in the engineering profession. He was not only a dedicated and passionate engineer, he was also a very approachable person who was always willing to help others.
"Ian was an absolute gentleman, and someone I fully respected for his advice on engineering matters. His experience and knowledge helped SOE to progress in the manner that it has, but it is his modest nature and sincerity that many people will remember him by.”
Ian was also involved with numerous charities, in particular working with dissafected young people.
SOE patron and former senior traffic commissioner Beverley Bell said: "I knew Ian for many years and throughout that time he always acted professionally and with the interests of SOE at heart.
"He was a man of complete integrity and his commitment to SOE was second to none. Everyone who worked with him thoroughly enjoyed his company, his down to earth approach and his dry sense of humour.”
