A Birmingham academic at the centre of a controversy involving one of the country's leading female detectives has died.
Prof Norman Dudley's friendship with Ellie Baker, the former head of West Midlands CID, sparked a misconduct investigation.
The detective was accused of manipulating the retired academic, who she had befriended at the Solihull church they both attended, into nominating her for honours.
His family also complained about gifts, including jewellery valued at about £20,000, he had given her.
Ms Baker, an officer for more than three decades, left West Midlands Police on New Year's Eve in 2004 after receiving a formal 'letter of advice' following an internal inquiry which cleared her of misconduct.
The inquiry led to West Midlands Police redrafting its guidelines on gifts and hospitality.
Prof Dudley, who died at the age of 89, was a hugely respected and celebrated pioneer of industrial education.
From 1956 until his retirement in 1980, he was head of the Engineering Production department at the University of Birmingham and was made a Commander of the British Empire in the Queen's Silver Jubilee Honours List in 1977.
Norman Alfred Dudley was born in Birmingham in 1916 and educated at King's Norton Grammar School and Birmingham Central Technical College. He was apprenticed to a firm of machine tool-makers, HW Ward & Company, at the age of 16 and remained in industry for 14 years.
Feeling a growing ambition to promote industrial productivity through education, he took an external degree and lectured at technical colleges in the Midlands, working to establish closer links between industry and higher education. In 1952, he was appointed to the University of Birmingham's newly formed Department of Engineering Production.
Having obtained his PhD in 1955, he was appointed Reader and Head of Department in 1956 and was elected Lucas Professor of Engineering Production in 1959.
From 1955 until Prof Dudley's retirement in 1980, he was director of the internationally renowned Institute for Engineering Production, a self-financed, residential study centre for senior academic and industrial staff.
He was also founding editor of the International Journal of Production Research from 1961 until 1980.
In 1963, he presented a paper at the United Nations Conference in Geneva on the Application of Science and Technology for the Benefit of the Less Developed Areas.
He initiated the biennial International Conferences on Production Research and in 1991 was honoured at the 11th International Conference held in the University of Science and Technology of China by the inauguration of a Norman Dudley Lecture.
Prof Dudley produced a report for the West Midlands Economic Planning Council in 1975 which highlighted the serious under-utilisation of machines and labour in engineering companies.
The Government then sought his advice on problems in industry and the effects of these on the economy of the Midlands.
He was elected a Fellow of the Fellowship of Engineering, founded on the initiative of the Duke of Edinburgh, which in 1992 became the Royal Academy of Engineering. Since his retirement, in 1980, Professor Dudley lived at Knowle in Solihull where he pursued a keen interest in genealogy. His wife, Hilda, died in 1998.
He is survived by his three children, five grandchildren and great granddaughter. The funeral service will be held at Coleshill Parish Church at 10.15am on Friday.
