He was the son of a banker from Lausanne and a member of the Dapples family, originally from the Canton of Vaud.
Following his football career, Dapples moved to Grezzano, a hamlet of Borgo San Lorenzo in Tuscany, where he lived in a villa (Villa al Monte) given to him by his uncle, Edmond Dapples, a retired surgeon.
He competed in six seasons of the Italian Championship, winning a total of five national titles.
In the 1910s, Genoa entrusted Dapples with the "Challenge Cup," also known as the "Coppa Duca degli Abruzzi," a trophy awarded to the club that won the first three Italian football championships.
After his death, the cup was lost and remained missing until 2018, when it was recovered and put on display at the Genoa Museum and Store.
