Captain John Treasure Jones RD, (15 August 1905 – 12 May 1993) was a British naval officer who became a well-known media figure in the mid-1960s following his appointment as the last master of the Cunard liner, RMS Queen Mary.

[a] John Treasure Jones was born on 18 August 1905, at Cuckoo Mill Farm at Pelcomb Cross, outside Haverfordwest, Pembrokeshire.

His father, Shrewsbury Treasure Jones, was a hay & corn merchant and ran the small 45 acre farm as a side line.

[b] In 1917 he gained a scholarship to Haverfordwest Grammar School, but did not complete his formal education as the possibility of employment on a ship came along, just a week before taking his final examinations.

[d] In November 1932 Jones managed to obtain employment as an assistant superintendent stevedore with Rea's Ltd, working with the Leyland Line ships at the Canada and Huskisson Docks in Liverpool.

Initially their task was to patrol the waters between Iceland and the Faroe Islands to prevent German supply shipping getting in and out of the North Sea.

On 4 November 1940, when returning to Liverpool from a patrol between Portugal and the Azores, Laurentic was torpedoed and sunk, 300 miles west of the Bloody Foreland in Ireland, with the loss of 49 lives.

Ninety percent of the crew had not been to sea before, but were strengthened and knit together by a small number of trained ratings and naval pensioners.

[5][g][h] In June 1945 Jones was promoted Acting-Captain RNR and posted to South East Asia Command under Admiral Mountbatten.

In 1964 Texaco completed a new oil refinery in Milford Haven, Pembrokeshire, just 10 miles from where John Treasure Jones was born.

In the autumn of 1965 it was announced that Mauretania would be withdrawn from service and sold to Ward's ship breaking yard in Inverkeithing, Fife in Scotland.

On 27 September 1967, Queen Mary arrived back in Southampton having completed her 1,000th and last crossing of the North Atlantic, having carried 2,112,000 passengers over 3,792,227 miles (6,102,998 km).

[citation needed] In August 1933 Jones married Eulalie Isobelle (Belle) Lees in Haverfordwest and they had three sons and a daughter.
