He is known for his work in combinatorial enumeration, polyominoes,[1] and box-packing.[2][5][3] Klarner was a friend and correspondent of mathematics popularizer Martin Gardner and frequently made contributions to Gardner's Mathematical Games column in Scientific American.[7] He edited a book honoring Gardner on the occasion of his 65th birthday.[4][9] Gardner in turn dedicated his twelfth collection of mathematical games columns to Klarner.[5] Beginning in 1969 Klarner made significant contributions to the theory of combinatorial enumeration, especially focusing on polyominoes[6] and box-packing.[7][8] Working with Ronald L. Rivest he found upper bounds on the number of n-ominoes.[2] Klarner's Theorem is the statement that an m by n rectangle can be packed with 1-by-x rectangles if and only if x divides one of m and n.[9][10] He has also published important results in group theory[11] and number theory, in particular working on the Collatz conjecture (sometimes called the 3x + 1 problem).[12] The Klarner-Rado Sequence is named after Klarner and Richard Rado.[13] BiographyKlarner was born in Fort Bragg, California, and spent his childhood in Napa, California.[14] He married Kara Lynn Klarner in 1961. Their son Carl Eoin Klarner was born on April 21, 1969.[15] Klarner did his undergraduate work at Humboldt State University (1960–63), got his Ph.D. at the University of Alberta (1963–66), and did post-doctoral work at McMaster University in Hamilton, Ontario (1966–68). He also did post-doctoral work at Eindhoven University of Technology in the Netherlands (1968-1970), at the University of Reading in England working with Richard Rado (1970–71),[16] and at Stanford University (1971–73). He served as an assistant professor at Binghamton University (1973–79) and was a visiting professor at Humboldt State University in California (1979–80). He returned to Eindhoven as a professor (1980–81), and to Binghamton (1981–82). From 1982 to 1996 he was a professor of computer science at the University of Nebraska, at Lincoln, with a one-year break at Eindhoven in academic year 1991-92. He retired to Eureka, California in 1997 and died there in 1999.[14] He was a frequent contributor to recreational mathematics and worked with many key mathematics popularizers including Ronald L. Rivest, John H. Conway, Richard K. Guy, Donald Coxeter, Ronald Graham, and Donald Knuth.[17][4][18][6] Organizations and awardsKlarner was a member of the Association for Computing Machinery, the American Mathematical Society, the Mathematical Association of America, and the Fibonacci Association.[14] He was awarded a National Science Foundation Fellowship Award in mathematics in 1963.[19] In 1986 Klarner received a University of Nebraska-Lincoln Distinguished Teaching Award in Computer Science.[20] The David A. Klarner Fellowship for Computer Science was set up after Klarner's death by Spyros Magliveras a fellow professor in Computer Science at UNL.[21] Bibliography
