first home defeat to France in 1948, they won their first Five Nations Grand Slam since 1911 in 1950. The next year, they lost 6–3 to the touring South Africans, despite dominating in the line-outs. They achieved another Grand Slam in 1952, followed by a 13–8 win over New Zealand in 1953. In 1954, St Helen's in Swansea (a Welsh international venue since 1882) hosted its last international and Cardiff Arms Park officially became the home of the Welsh team. In 1956, Wales again won the Five Nations, but they did not regain the title until 1964 and did not win it outright until 1965. Wales conducted their first overseas tour in 1964, playing several games and one test in South Africa. They lost the test against South Africa in Durban 24–3, their biggest defeat in 40 years. At the WRU annual general meeting that year, the outgoing WRU President D. Ewart Davies declared that "it was evident from the experience of the South African Tour that a much more positive attitude to the game was required in Wales ... Players must be prepared to learn, and indeed re-learn, to the absolute point of mastery, the basic principles of Rugby Union football". This started the coaching revolution. The WRU Coaching Committee – set up in the late 1950s – was given the task of improving the quality of coaching and, in January 1967, Ray Williams was appointed Coaching Organiser. The first national coach, David Nash, was appointed in 1967 to coach Wales for the season, but resigned when the WRU refused to allow him to accompany Wales on their 1968 tour of Argentina. Eventually, the WRU reversed their decision, appointing Clive Rowlands to tour as coach. Of the six matches, Wales won three, drew two and lost one. Second 'golden age' (1969–1979) Wales enjoyed a second "golden age" in the 1970s, with world-class players such as Gareth Edwards, J. P. R. Williams, Gerald Davies, Barry John, and Mervyn Davies in their side. Wales dominated Northern Hemisphere rugby between 1969 and 1979, and managed an incredible winning record, losing only seven times during that period. Wales toured New Zealand for the first time in 1969, but were defeated in both matches. In the second test, which they lost 33–12, New Zealand fullback Fergie McCormick scored 24 points; a record at the time. In 1970, Wales shared the Five Nations with France,
