Born in Cardiff in 1929, Thomas was sent to Blundells School in Tiverton, Devon. He was one of the few schoolboy players good enough to be recognised outside his homeland and picked to represent his country. His debut for Wales came at Cardiff Arms Park in 1946 when the Welsh Secondary Schools Under 19 team defeated the English Public Schools side 11-9.
At the time he was described as "a hardworking, fast and intellingent wing-forward". He never lost those qualities in his senior career, yet added a steely, uncompromising edge to his play.
He won three more Schoolboy caps in 1946 and 1947, never ending on the losing side, before going up to Cambridge. He won a blue in their 1949 defeat by Oxford, yet a year earlier had helped the students rob Cardiff of its 18-month ground record with a magnificent triumph at the Arms Park.
He first played for Wales in the final game of the 1949 Five Nations Championship against France at Stade Colombes, Paris. It proved to be an inauspicious start for the 20-year-old as Wales slumped to their third defeat of the series and picked up the Wooden Spoon. He had to wait three years and 12 games for his next international, which proved a far more agreeable experience.
This time Wales ran out as 14-3 victors over Ireland at Lansdowne Road. Thomas scored a try and made another and Wales became winners of the Triple Crown. He quickly developed into a permanent fixture, and captained his country nine times in 1958 and 1959, leading them to five wins.
Arguably his most famous moment came in the 1953 international at the Arms Park against New Zealand. He had been in the Swansea side that had held the All Blacks to a 6-6 draw a week earlier, but played a major role in helping Wales to go one better on 19 December 1953. The game was locked at 8-8 with five minutes to play when Thomas, who had earlier done duty as an emergency wing while Gareth Griffiths was having his dislocated shoulder replaced, snatched up the ball on the All Blacks' 22 on the south- stand side.
He looked across the field to the wide open spaces and let fly with the most famous cross-kick in post-war rugby. Ken Jones, Wales' Olympic sprinter on the wing, raced in to gather the bouncing ball, swerved past the New Zealand full-back Ron Jarden and scored at the posts.
Wales won the game 13-8 and Thomas joined the ranks of those Welsh immortals who have played on a winning side against New Zealand - Wales has not won against them since.
For Swansea, he played in the sides that fell to narrow defeats against the 1951 Springboks and 1957 Wallabies, but he led the Welsh team to a 9-3 triumph over Australia in 1958.
The determination of the man was best epitomised by his refusal to return from the British Lions tour of South Africa in 1955 after having his appendix removed. Although he missed the first two tests, he went on to play a vital role in the 3rd and 4th tests, helping the Lions share the series, including the 9-6 win in Pretoria.
His 26th and final cap came against France in 1959 - like his debut, a defeat in Paris. No sooner had he hung up his boots than he picked up the pen and begun a career in journalism.
A wholesale butcher by trade, he also worked as the Observer's chief rugby writer for almost 35 years. Two years ago he stepped across the broadsheets to write for the Independent on Sunday.
He was twice rewarded in the annual Whitbread/Rugby World Honours for his services to journalism and could light up any press box or press conference. He wrote the book Welsh Rugby with Geoff Nicholson in 1980 and was in the process of proof-reading the official history of the Lions.
A larger-than-life character, in the 1970s he twice stood as a Liberal candidate, for the Gower and Carmarthen constituencies and in 1979 as an MEP, for Wales Mid and West.
