Vol. 8 No 7 - Pi Mu Epsilon

puzzle or problem for mathematicians." Singlehandedly he was soon
editing 10 issues a year, each 30 pages in length, a monumental task
for any person. Rarely could you find an error on its pages, so
careful was its editor. He personally verified every mathematical
statement that appeared on its 300 pages each year. His wit and
fluency in both French and English made the journal lively and
exciting, as well as informative. Early in 1986 L ~O retired because
of ill health, after having built Crux into a journal with
subscribers and contributors throughout the world. He died in June,
1987. Therefore it is our privilege to dedicate this issue of the
Problem Department to the memory of ~ 6o ~auv6, a true scholar and
friend, and to express our hope that we will always be guided by his
spirit in our editing of these pages.
