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.[3]
Archdeacon was born on May 11, 1954, in Dayton, Ohio, and grew up in Centerville, Ohio. 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.[1][3] He died of cancer on February 18, 2015, in Burlington, Vermont.[1]
In 2003–2004, the University of Vermont named him as University Scholar.[2][3] A special issue of the Australasian Journal of Combinatorics was published in his honor in 2017.[1]
