Myles Tierney was a Rutgers faculty member for thirty-four years, coming to Rutgers as an Associate Professor in 1968 following positions at Rice University (1965-6) and at the ETH-Forschungsinstitut für Mathematik, Zürich (1966-68). He received his B.A. from Brown University in 1959 and his Ph.D. from Columbia in 1965.
Myles began his career as an algebraic topologist, moved toward category theory and was responsible (together with F.W. Lawvere) for the introduction of a new field within category theory: elementary topoi.
He had six Ph.D. students: Ira Wolf (1971), Carol Ann Keller (1983), Norman Adams (1984), Terence Lindgren (1984), Todd Trimble (1994), and Luca Mauri (1998). Myles retired as of January 1, 2003 and was honored by the Department at a retirement party on December 10, 2002.
