John Rosamond was, like the British motorcycle industry, born in the West Midlands. After leaving school, he learnt his trade as a skilled welder and shortly thereafter was employed by the world famous Triumph motorcycle factory at Meriden to work producing their new oil-bearing frames. A socialist and union man, John was elected to speak on behalf of his fellow welders. Returning to welding frames after the Meriden sit-in, John became, in 1977, the second and last chairman of the Triumph workers' board of directors in particular, seeing through the continuing development of the world famous Bonneville model until the factory's closure in 1983. After Meriden, John was employed by the new Triumph firm in Hinckley and then returned to his original trade as a welder, assessing students in the craft until his retirement in 2003.
