text_A: Before 1920, the university declined to give academic degrees to women and would not acknowledge them as full members of the university. (Some of these women, nicknamed the steamboat ladies, were awarded "ad eundem" degrees by Trinity College Dublin, between 1904 and 1907.) In 1920 the first women graduated from the college at the Sheldonian Theatre and the principal at the time, Henrietta Jex-Blake, was given an honorary degree.
text_B: Was there a law forbidding young women from obtaining academic degrees after 1920?
DON'T KNOW.
