Dan Steven Archdeacon (1954–2015) was an American graph theorist specializing in topological graph theory,[1][2] who served for many years as a professor of mathematics and statistics at the University of Vermont.
He did his undergraduate studies at Earlham College, graduating in 1975.
[1] He completed his Ph.D. in 1980 from Ohio State University, under the supervision of Henry Hatfield Glover, with a dissertation proving an analogue of Kuratowski's theorem for the projective plane.
[4] He took a position at the University of Vermont in 1982, joining fellow graph theorist and Ohio State graduate Jeff Dinitz, after previously working as an instructor at the University of Kansas.
[2][3] A special issue of the Australasian Journal of Combinatorics was published in his honor in 2017.
