zht Young Bidchemist Motherhood ‘Myth’ Miffs Mother Who Works By Sue Cronk AN AWARD-WINNING Washington biochemist who combines a more-than-full- time job with marriage and mo therhood ina “will have no truck with the great American myth that children turn out terrible if their moth- ers are not at home to watch them every day.” On weekdays, Maxine F. Singer sees her three Miss Cronk youngsters — Amy, 4, Ellen, 2, David, 11 months—only briefly. “Yet I think my children are happy, alive, interested in the world around them, and not difficult to deal with,” she said last week. Mrs. Singer always tries to get home on time from her job at the National In- stitute of Arthritis and Met- abolic Diseases to play with the children before their bedtime. Even when she is in the middle of an experiment and is “tempted to stay late” in the laboratory, she heads for home, “taking my paper work with me to do late at night. The men around here can work much longer hours that I, but that’s one of the compromises one has to make.” At home, near Chevy Chase Circle, the children’s hour ends when the supper hour begins. She and her husband, at- torney Daniel M. Singer, “eat alone, because if the children ate with us, we’d never have a chance to talk.” The children get their say on weekends, when the Singers take them to play- grounds and read to them. A PETITE, 32-year-old brunette with an “Oliver” haircut and green eyes, Mrs. Singer met her husband when both were students at Swarthmore College. Although her primary in- terest is in biology, she took her bachelor’s degree in chemistry “because I felt that one understands more about biology through chem- istry and nothing I’ve learned since thet has ever dissuaded me ‘rom this view.” : She earned a FhD. in bio- chemistry at the National Science Foundation at Yale University aad came to NIAMD as a postdoctoral fellow. Now a permanent a member, she is a GS- In a ninth floor laboratory in the sprawling red brick Clinical Center at the Na- tional Institutes of Health, she works on the chemistry of heredity in the general area of nucleic acid. For her contributions on the mechanism of action of the enzyme polynucleotide phosphorylase -—- “which cat- alyzes the chemical reaction which results in the forma- tion of nucleie acid-like ma- terials” she recently re- ceived the Iota Sigma Pi Re- search Award. The award, which carries a $300 honorarium, is given every three years by the na- tional honorary society for THE WASHINGTON POST 86 “4 “Saw. Sel at a Sundav, Juz.

It would be impossible not to be excited. The curve is just cresting. If you stay away from your work for two weeks, you’re behind.” Nevertheless, she left yes- terday with her family for a month-long vacation at Bethany Beach, Del. “The schedule I'm on is very ex- hausting, and I feel the need of a long vacation,” she said. But she took a briefcase “full of lab work” in addi- tion to a bathing suit.
