Glenda Reiser (Can) died of a long illness recently, she was 52. All I know of her for sure is that she ran 4:06 at age 17 in the Munich Games 1972. She ran well the next year; after that, I could find no results. She went on to become an MD.
For comparison, the U.S. age 17 girl's record is over 10 seconds slower, 25 years later.
