Governor Biographies


Wim Bushell – Chair of Governors


Wim is the Deputy Chairman of Gallagher London, a global insurance company. His education at Millfield as a boarder in Walton (1970 – 1973) fuelled his passion for sports and as well as participating in a wide variety of sports (amongst which football, cricket and rugby) he gained first team colours in football. After leaving Millfield, his interest in sports did not dwindle and he continued to play for two seasons for Corinthian Casuals AFC, swapping sports afterwards to play for Richmond RFC, also captaining the infamous Richmond ‘Heavies’. Additionally, he was captain of Lloyd's Gentlemen's Rugby XV. Wim is a keen golfer and is also a member of the MCC.

In 1974, Wim went to work for a small insurance brokerage firm (Wigham, Richardson and Bevington) in the City. In 1987 he became a partner in a company called MRC Limited, which sold itself, in 1996 to a Chicago based brokerage firm, Arthur J. Gallagher, where he became Managing Director, then Chairman of the Reinsurance arm. After this company was acquired by Aon Corporation, another Chicago based operation, Wim became Deputy Chairman for Aon Re UK and has since returned to Arthur J Gallagher as Deputy Chairman of Gallagher London. As well as having been educated at Millfield, Wim was an Old Millfieldian Society committee member in 2003 - 2006. He joined the Foundation Committee from 2007 – 2008 and was appointed a Governor in 2009.


Robert Thornton


Bob attended school in Dublin and London before reading for a BA (Hons) in French and English at London University. He spent three years as an airman in the RAF and another three in various occupations before deciding he wanted to be a school teacher.

He was appointed to his first headship in 1986 of a catholic comprehensive school in Bristol where he remained until 2004. During his 18 years in this post he was asked on several occasions if he would seek permission from his governors to be seconded as temporary headteacher to a number of secondary schools in Bristol that for various reasons were experiencing some difficulties. When he resigned his substantive post in 2004, he was invited by the Director of Education for Bristol to take on the leadership of Withywood School which was designated to become the Merchants' Academy in new buildings in September 2008.

Bob retired in August 2008 but after a year of ‘retirement' he was engaged by Oldham Education Authority to do some school leadership development and then to take the role of ‘interim headteacher' in a co-educational 11-18 comprehensive school with over 1,200 pupils on roll. He now acts as an educational consultant.

Bob has been a Governor in a number of secondary and primary schools including one of Bristol's oldest independent schools, and was appointed as a Governor at Millfield in 2010.
