John Svanberg
Johan Frithiof Isidor "John" Svanberg was a Swedish runner. He competed in the 5 miles and marathon at the 1906 Intercalated Games and 1908 Summer Olympics and won two silver and one bronze medals. In 1908 he set a world record over 3000 m that stood until 1911.
After the 1908 Olympics Svanberg was deprived of his amateur status for some commercial activities. He moved to the United States, where he worked as a painter and continued competing in running. He died in New York in 1957.
