In 1940 Blackmur moved to
Princeton University at the invitation of
Allen Tate. There, he taught first creative writing as Associate of Creative Arts and then English literature for the next twenty-five years, famously in spite of having only, officially, a high school education. He initially struggled to keep his place, but finally became a full professor in 1951. Along the way he began to betray Tate, for instance spreading malicious gossip that Tate was a
Nazi sympathizer, leading Tate to leave and later resent Blackmur's Machiavellianism. Blackmur and his wife divorced in 1951 after years of marital strife, mutual dissatisfaction, and infidelity on her part. He continued to publish poetry, particularly the collections
The Second World (1942) and
The Good European (1947). He met other influential poets while he taught at Princeton including
W. S. Merwin and
John Berryman. Merwin later published an anthology dedicated to Blackmur and Berryman and a book of his own poetry (
The Moving Target) dedicated to Blackmur. In 1952, Blackmur's collection of poetry criticism
Language as a Gesture collected several of his previous critical essays from
The Double Agent and
The Expense of Greatness as well as several new essays on the poetry of
W. B. Yeats,
T. S. Eliot,
Ezra Pound, and
Wallace Stevens. While at Princeton, Blackmur became an important literary expert for the
Rockefeller Foundation via a friendship from his Cambridge days with Rockefeller associate director John Marshall (1903–1980). In 1947, he was awarded a
Rockefeller Fellowship. He was a member of the
Century Association. He founded Princeton's
Gauss Seminars in Criticism in 1949, funded by the Rockefeller Foundation and named in honor of his colleague, Princeton dean
Christian Gauss, and he officially directed these seminars 1957–1965. He was invited to give a series of four lectures on the literature of 1921–1925 at the
Library of Congress in 1956. Blackmur taught at
Cambridge University in 1961–62. In this later phase of life, for instance in
The Lion and the Honeycomb (1955), he became politically engaged, particularly with issues of university standards and reform and with rival critics such as
Lionel Trilling; he was opposed to the
Partisan Review group. == Death ==
