At the risk of sounding even more Gingrichian, I am extremely uncomfortable with single parenting, with the European tradition of having only one professor supervise, support and sustain the aspiring classicist. It allows the professorial parent too much control, and can be risky for the offspring if something unfortunate happens to either the relationship or the professor. I myself do not teach in a department which offers the Ph.D., but have taken on numerous parental commitments for graduate students and recent Ph.D.'s from other institutions. So much of what we do involves confidential deliberations, and can't appropriately be shared. Many of my own mentors, even the ones I sought out myself, enjoy privileged existences in sheltered academic environments, and haven't a clue about what my life at a large, financially strapped, demographically diverse public institution is like.
Comment seems superfluous.
Capland did not follow this advice. For a general treatment of anti-Semitism in the American sciences, cf. Caplan was not deterred by this doubtless well-meant counsel, and in fact his rapid advancement in his profession seems not to have been impeded by prejudice. His promotion to the rank of professor in 1930 at the age of 34 long antedated the influence of refugee scholars, who are thought to have opened the gates for American Jewish classicists.
