Stirling Moss missed out on the 1958 Formula One title by a single point to which opponent?

John Michael Hawthorn (10 April 1929 – 22 January 1959) was a British racing driver. He became the United Kingdom's first Formula One World Champion driver in 1958, whereupon he announced his retirement, having been profoundly affected by the death of his teammate and friend Peter Collins two months earlier in the 1958 German Grand Prix. Hawthorn also won the 1955 24 Hours of Le Mans, but was haunted by his involvement in the disastrous crash that marred the race. Hawthorn died in a road accident three months after retiring; he was allegedly suffering from a terminal illness at the time.

Mike Hawthorn was threatened with a penalty after the Portuguese Grand Prix, Stirling Moss defended him. Hawthorn was accused of reversing on the track after spinning and stalling his car on an uphill section. Moss had shouted advice to Hawthorn to steer downhill, against traffic, to bump-start the car. Moss's quick thinking, and his defence of Hawthorn before the stewards, preserved Hawthorn's 6 points for finishing second behind Moss. Hawthorn went on to beat Moss for the championship title by one point, even though he had won only one race that year to Moss's four.
