Frederick Gilroy was born on 7 March 1936 in Belfast, Northern Ireland. Getting an early career start, he joined the St. John Bosco amateur boxing club at the age of nine. At the 1956 Summer Olympics in Melbourne, he won a bronze medal in bantamweight boxing. After a first round bye, Gilroy defeated Boris Stepanov of the Soviet Union by a third-round knockout. He then beat Mario Sitri of Italy on points, before losing to Wolfgang Behrendt of Germany on points.
Pro career
Taking the British Empire and European Bantamweight titles, 1959
Johnny Morrisey fell to Gilroy in an eighth round knockout in Belfast on 17 September 1958 in the second round eliminator for the Commonwealth Bantamweight title. On 10 January 1959 he defeated Peter Keenan decisively in an eleventh round TKO in Belfast, Northern Ireland, to take the Commonwealth Bantamweight title. Most effective in the match was Gilroy's left hook. Keenan was floored in the third by a left hook, and was down for an eight count in the eighth. In the tenth, Keenan was twice down for counts of nine, before a towel from his corner signaled the end of the bout. Keenan, the former champion, fought courageously to stay in the bout as long as he did. On 3 November 1959 he took the EBU European Bantamweight title from Italian Piero Rollo in a narrow fifteen round points decision in Wembley, London. He successfully defended the British Empire Bantamweight title against South African Bernie Taylor on 5 December 1959. Winning in a fifth round knockout in Belfast, Northern Ireland, he retained his title in a decisive victory.
Contending for the World Bantamweight title, 1960
In 1960 he fought Alphonse Halimi for the World Bantamweight title but lost on points in London. Gilroy, the reigning European and British bantamweight champion, was the favorite of the partisan British crowd. Halimi scored the bout's only real knockdown with a short right hook in the thirteenth round for a count of five. Halimi slipped once to the mat in the seventh without taking a count. On 20 October 1962, Gilroy fought fellow Belfast native and Olympic medalistJohn Caldwell in what is widely regarded as one of the greatest fights ever to be held in Ireland. Gilroy won when a cut to Caldwell's eye prevented him continuing the bout. He retained his British Empire Bantamweight title, and immediately announced his retirement from his short but successful boxing career. He died at the age of eighty in Belfast, Northern Ireland on 28 June 2016. His funeral was at Holy Cross Church in Belfast.
