Selma Landsberg

Executive Secretary (1978 - 1996)
MOEMS Board Member

Mrs. Landsberg is a member of the MOEMS Board of Directors for life. For seventeen years (1979 - 1996) she was Executive Secretary, the friendly voice on the phone so well known to so many PICOs. In 1978 as Dr. George Lenchner began to design the Math Olympiads for the Valley Stream, NY school district, he was assigned an office adjoining the one in which she was a secretary. His excitement over his new project was so electric, she felt compelled to help, willingly working during lunch and after school. Rapid growth forced both of them to retire in 1983 to devote themselves fulltime to the Olympiads. She controlled all recordkeeping until her retirement, guiding it from handwritten formats she processed alone, to handwritten formats she processed with help from several volunteers (including her whole family), and then to a computerized format she processed alone using a computer program designed in 1983 by John Botti, a high school student. In her final year, 1995 - 1996, she processed about 3210 teams - by herself. The procedures she designed are still in use today, with minor modifications.

Dr. George Lenchner

Executive Director, 1978-1995

Dr. Lenchner has distinguished himself in many diverse areas. He was a member of a championship high school math team in the mid-1930s, was All-America in Lacrosse at CCNY, was seriously wounded on D-day in 1944, spending over a year in hospitals, and earned a Masters degree in music in 1948 -- all before deciding to focus on math education. In 1950 he became a high school mathematics teacher. In 1965 he received an MS in Mathematics from Adelphi University and in 1972 an Ed.D. in Mathematics from T.C. Columbia University.

In 1955 he created the Nassau County (NY) Interscholastic Mathematics League (NCIML) for high school students, perhaps America's first regional math contest outside of New York City run by the schools themselves. Five years later, he created a similar junior high school league for Nassau County. His article in the Mathematics Teacher (NCTM, February 1959) on the NCIML sparked the formation of similar leagues by many county and state math organizations across the nation. In 1970 he became Director of Mathematics for the Valley Stream School District, working with elementary schools for the first time. His inservice course, The Art of Problem Solving in School Mathematics, meant for Valley Stream teachers, eventually became a book for Houghton Mifflin, one of many books and articles that he authored or co-authored for major academic publishers. A master teacher, his students include several prominent mathematics educators and his workshops have inspired people on four continents to participate in the Math Olympiads.

Among his honors are: National Science Foundation Fellow; HEW Department Fellow; Mathematics Teacher of the Year Award, NYS Society of Professional Engineers; Distinguished Secondary School Teaching Award, Harvard University; Distinguished Achievement Award for Excellence in Educational Journalism, EPA of America; Founder's Award for Outstanding Service, NCIML; LIMACON Award for Outstanding Contributions to Mathematics Education, Long Island Mathematics Conference; Goudreau Award for Outstanding Contributions to Mathematics Education, Goudreau Museum of Mathematics and Science.
