George Lenchner (1917-2006) was born in
Hartford, Connecticut, and grew up in Brooklyn, New York. He was interested in
mathematics early in his life, and was a member of the math team at Boys High
School (Brooklyn, NY) in the early 1930s. In 1939, Lenchner received his
bachelor's degree from the City College of New York.
During WWII he served in the Army as an Airborne Ranger (with the rank
of lieutenant), and in 1944, he was wounded on Omaha Beach during the D-day
landing operations. He was awarded a Purple Heart and a Bronze Star. Following
his service in the Army, he received his master's degree in music from New York
University in 1948.
Lenchner began teaching high school mathematics in
1950 when he joined the faculty at New Utrecht High School in Brooklyn. In
1953, he took a job at Valley Stream North High School (Long Island, NY) as its
math chairman. In 1954, he proposed the creation of the Nassau County (NY)
Interscholastic Mathematics League (NCIML) for high school students. By 1955,
the NCIML was fully operational, with Lenchner serving as its leader. Also
around this time, he formed the Nassau County Association of Math Supervisors,
and he proposed the formation of the Nassau County Junior High School
Mathematics League, which held its first meet in 1960. In addition, Lenchner
helped Alfred Kalfus form the Suffolk County Interscholastic Mathematics
League.
In 1965, he earned a master's degree in mathematics from Adelphi
University. He became Director of Mathematics for the Valley Stream Central
School District in 1970. In 1972, Lenchner received his Ed.D. in Mathematics
Education from Teachers College, Columbia University. He created the
Mathematical Olympiads for Elementary and Middle Schools (MOEMS) for the Valley
Stream elementary schools in 1978. Lenchner retired from the Valley Stream
school system in 1983 in order to focus fully on MOEMS. He retired from MOEMS
in 1995.
Lenchner authored numerous publications, including (with Judy
Broadwin) a solutions manual for the Advanced Placement examinations in
calculus, and two volumes of Math Olympiad problems. His in-service course, The
Art of Problem Solving in School Mathematics , was published by Houghton Mifflin
in 1983, with the title Creative Problem Solving in School Mathematics.
Examples of his honors and awards include being named a National Science
Foundation Fellow, the Mathematics Teacher of the Year Award from the New York
State Society of Professional Engineers, and the Distinguished Secondary School
Teaching Award from Harvard University.
Correspondence, lectures, notes, and publications document George
Lenchner’s career as a teacher and administrator in the Valley Stream Central
School District (1953-1983). The publication process for several of Lenchner’s
published works is particularly well documented in drafts and correspondence
with his son, David. Correspondence, notes, drafts, and printed materials
illuminate Lenchner’s work as founder and later executive officer of Math
Olympiads for Elementary and Middle Schools.
