Nelson Goodman

Goodman received his doctorate from Harvard in 1941. He's not listed among the Quine students, so his advisor must have been someone else. His book A Study of Qualities came out in 1941, so I'm assuming it was his dissertation.

Update: I've now put Goodman under C.I. Lewis in the tree.

Gwil Owen

Owen's students at Harvard in the 1960's and 1970's have included Martha Nussbaum, Gail Fine, John Cooper, and Julia Annas. Other than Nussbaum's comments, I don't really know much more about him, including where and when his education was received.

Update: Owen has been placed under Gilbert Ryle in the tree.

Benson Mates

Mates was teaching at Berkeley at least as far back as 1960. He was born in 1919, so the likely date of his graduate education is around 1944-1950. Nothing else to go on, I'm afraid.

Ledger Wood

I don't have much to go on here. Some remarks in Rescher's autobiography suggest that Wood might have been his dissertation advisor, and Rescher wrote a dissertation on Leibniz in the 1940s at Princeton. I checked a book of Wood's (The Analysis of Knowledge), and it lists some colleagues in the acknowledgements, but no genealogical influences

Frederic Fitch

Fitch received a doctorate from Yale in 1934. I've no idea who was at Yale in that period doing logic, so I can't even make an educated guess on his teacher. I see that Alan Ross Anderson lists Fitch and von Wright as his principal teachers in the introduction to Entailment -- any information on which of the two was primary, or more official?

Update: I've placed Fitch under Filmer Northrop in the tree, and Anderson under Fitch.

Max Black

Black was influenced by Russell, Wittgenstein, Moore, and Ramsey while an undergraduate at Cambridge, but he received a doctorate from the University of London in 1939, so I'd like to find his advisor for that degree to use for his parentage. Anyone know anything useful?

Update: I've placed Black under Susan Stebbing in the tree.

Herbert Heidelberger

Heidelberger taught at UMass [thanks to Ben for the correction] from 1967 until his death at 1982. I don't know how far prior to 1967 he received his doctorate (there are publications going back at least to 1963), or where he received it. Anyone know anything more?

Gregory Vlastos

I know Vlastos received a doctorate from Harvard in 1931, but I have no further information. Does anyone know, or care to speculate on, who his advisor was?

Update: Vlastos refers to Whitehead as his supervisor in the introduction to Socrates: Ironist and Moral Philosopher, so I'm going with that.
