This lift appears to be Olsen’s third Snatch attempt of 112.5 kg (which was not passed.) Olsen briefly held two official and one unofficial world records but retired shortly afterwards to become a strongman at the Circus Meihe.
Manger kept at it, and went on to win three national lifting championships, one in the 181 lb. class in 1929 and two light-heavyweight crowns in 1930 and 1932. Manger finished fifth with a 315 kg. total at the 1932 Los Angeles Olympic games. Manger also won regional championships in the shot put and weight throwing.
…Pretty good for a skinny kid from Baltimore.
If you would like to learn about the specific types of training that helped Manger build his strength, you’ll find it in The Alan Calvert Collection.
If you had one of these in your back pocket on July, 31st, 1932 you would have gotten to see Raymond Suvigny of France set the Olympic record in the Featherweight class with a 287.5 kg total, the great German lifter Rudolf Ismayr take the Gold in the middleweight class with a 345.0 kg total (also an Olympic record) and Jaroslav Skobla, the Czechoslovakian champion take the Gold in the heavyweights with a 380 kg total.
