Upsala Simsällskap, or Uppsala Swimming Society in English, is considered the world's oldest swimming club. The club was founded to provide elementary swimming instruction. It began offering competitive swimming in 1910 and remains a successful swimming club in Sweden today.
Svanberg arranged a mock "graduation ceremony" (simpromotion) modeled after the less-rigorous academic ceremony, where he and some of his colleagues awarded themselves the master's degree ([[magister]]) and their pupils the degree of bachelor ([[kandidat]]) in swimming. Gabriel Marklin and Carl Gustaf Grahl succeeded Svanberg as leaders of the club.
