Tory was a fifth generation civic head; OBITUARY.
Mr Martineau died peacefully in hospital on Wednesday at the age of 79.
His funeral will be held next Friday at St George's Church in Westbourne Road, Edgbaston. The civic diary has been reorganised to allow councillors time to attend the funeral, which will be followed by a service at Lodge Hill Crematorium in Weoley Park Road. A memorial service may be held later this month.
The former Tory councillor leaves a widow, Mollie, and three sons, Jeremy, Peter and Charles.
Mr Martineau was the last in the family's line to serve the city, a first, according to the Guinness Book of Records.
He was preceded by his great-great grandfather Mr Robert Martineau (1840) and Sir Thomas Martineau (1884-87), who was knighted by Queen Victoria when she opened the Law Courts.
The title was changed in 1896 to Lord Mayor, which paved the way for his grandfather Mr Ernest Martineau (1912), and his father, Mr Wilfrid Martineau (1940).
Finally, Mr Denis Martineau took up the mantle, which had become something of a family tradition, in 1986-7, and then became deputy mayor in 1987-8.
His civic career began in 1961 when he was elected as councillor for Edgbaston, and continued to serve until 1991 when he stepped down.
He was a member of the bank, water and children's committees prior to local government reorganisation, and then served on the NEC Committee (1980-1991) and the Joint Consultative Committee for nine years. In May, 1991, Mr Martineau was made an honorary alderman in recognition of his long service to the city council.
Born on April 5 1920, he was educated at Rugby School and Trinity College, Cambridge.
Commissioned in the Royal Warwickshire Regiment, he served in the Army between 1940 and 1946 in the Middle East, North Africa and Italy. He remained a partner in Ryland, Martineau and Co solicitors until he retired in 1984.
In 1988, he was made an officer of the Order of St John, an honour awarded by the Queen for services to the community.
Mr Martineau's family has requested family flowers only, with donations to be made to St John Ambulance or the Birmingham Symphony Hall Organ Fund, c/o W H Scott & Son, funeral directors, 426 Rotton Park Road, Edgbaston, Birmingham B16 0LA.
