Nice job, jmd. Athlete A is Jack Torrance and athlete B is Silke Gladisch.
Jack Torrance broke the shot put WR three times in 1934, and that's just the official count. Before that year, the WR was at 16.20; once he was finished, it was at 17.40 and would remain there until Charles Fonville came along in 1948. (As noted in this thread
, Fonville weighed some 100 pounds less than Torrance!)
US outdoor champion in 1933-35 and NCAA champion in '33 and '34 in the SP, Torrance was also a useful discus thrower and one of the key performers when LSU won their first team title in 1933. After placing 5th in Berlin and subsequently retiring from T&F he briefly became a professional boxer, and later a football player; he was with the Chicago Bears when they won the NFL championship in 1940.
As noted, Silke Gladisch (-Möller) won the 100/200 double in Rome '87; her winning time of 21.74 in the latter race was only 0.03 from the world record and still stands as the CR. Her third gold was from the 4x1 relay in '83; in both '87 and '88 the East German relay team had to be content with silver.
