Abel Wolman noting Rosh Hashanah, Yom Kippur
Abel Wolman ('13) during his professional career notes in his diary Rosh Hashanah (on an earlier page) and Yom Kippur, indicating his taking those days off. There is no mention of other holidays (except Passover in some years) or of taking Friday evenings or Saturday off. This is likely a similar level of observance to many of his peers in the early stages of the University.
