Charles Georg Lomberg (4 December 1886 – 5 March 1966) was a Swedish decathlete. He competed at the 1912 Summer Olympics in the long jump, pentathlon and decathlon and finished in 17th, 16th and third place, respectively.[1] He was awarded a silver medal in the decathlon after the disqualification of Jim Thorpe. In 1982 Thorpe was reinstated as the champion, yet Lomberg retained his second position and silver medal.
Lomberg won the 1912 Swedish decathlon title, beating Hugo Wieslander, but lost to Wieslander at the 1912 Olympics. He actively competed only in 1911–1912, and tried to qualify for the 1920 Games, but failed.
