Mark R. Leeper passed away on February 22, 2025.  His end was very 
peaceful; one moment there was a breath, and the next there wasn't.

Mark was born in Chicago in 1950, and has lived in Chicago, West 
Virginia, Ohio, Massachusetts, California, Michigan, and for the last 47 
years, New Jersey.  He received a B.S. in mathematics from the 
University of Massachusetts in 1972, an M.S. in mathematics from 
Stanford University in 1974, and an M.E. in electrical engineering and 
computer science from Stevens Institute of Technology in 1982.  While at 
Stanford, he had a paper published in aequationes mathematicae (Vol. 
10, Fasc. 1, 1974) on which he had begun work as an undergraduate, “An 
Odd Solution to the Functional Equation P((x+1)/2)=exp P(x)”.  He was 
employed at Bell Laboratories in Holmdel and surrounding locations for 
23 years until his retirement in 2001.  After retiring he ran a free 
drop-in math tutoring session twice a week for a dozen years at the Old 
Bridge Public Library, and when he had to leave for health reasons, it 
was continued by some of the students he had tutored.

For many years, Mark had been the longest-running film reviewer on the 
Internet, regularly publishing reviews since 1984, and being a member of 
the Online Film Critics Society since 2014.  His first science fiction 
convention was Boskone VI (1969) and he attended dozens of conventions, 
serving on panels about film, and also leading origami workshops at many 
of them.  In 1978, Mark and his wife founded the science fiction club at 
Bell Laboratories in New Jersey, which existed until their retirement in 
2001, and then continued to produce THE MT VOID, a weekly zine featuring 
Mark's editorials and film writing.  It was published continuously over 
46 years, with over 2300 issues.  Mark traveled to about five dozen 
countries and published several lengthy travelogues on-line.  He leaves 
behind him his wife of 52 years Evelyn, sister Sherry, brother David, 
and many cousins, nieces, nephews, godchildren, and friends.

In lieu of flowers, contributions may be sent to the UMass Amherst 
Foundation, for the Leeper Mathematics Scholarship.
