Bob McGregor’s prowess in the pool should have come as no surprise – his father, David, was an Olympic water polo player – but like many of Scotland’s leading swimmers he trained in a 25-metre pool.
As swim team captain at the Tokyo Games in 1964, he won the silver in the 100m freestyle and took another silver in the same event at the 1966 Commonwealth Games. That was quickly followed by a European Championships gold medal, then a new world record of 53.3secs in the 100m at the British Championships.
He retired from competitive swimming after the 1968 Olympics and was awarded the MBE the same year. He later worked as an architect in Glasgow.
