19-year-old William Francis Billy O'Connor was the first person to complete a crossing of lac Memphrémagog. His swim on 21 August 1955 took 18 hours 35 minutes, swimming from south to north despite a storm that hit near midnight and caused him to take refuge near the side of the lake.
O'Connor had a 10-minute break every hour to replenish his energy and power. His successful swim was the inspiration for the Traversée Internationale du Lac Memphrémagog, a professional marathon swim started in 1979, a distance of 42 km between Prouty Beach, Newport (USA) and Pointe Merry in Magog (Quebec).
