Marguerite McKay Casselman was a beloved teacher with Mission School District No. 75 for 30 years. She began her career in 1922, when the school occupied temporary quarters in the Agricultural Building on the Fair Grounds. The first High School was built on Seventh Street, and she taught there from 1922 to 1929, after which she took up the position of principal of Matsqui Superior School for two years. She returned to Mission High School for the remainder of her career, from 1932 to 1954.
Known affectionately as “Cassy”, Marguerite taught the many generations of the Mission community, and never forgot her students or their names. She was accustomed to saying that her motto in life was “Live, be happy, and in short, keep alive”. She had two siblings, never married, and was happiest at her home on Mount Mary Ann, overlooking the Fraser Valley landscape.
When she retired, a full-page tribute in the 1953-54 issue of “The Flame”, Mission High School’s Annual, was dedicated “To Our ‘Cassy’ with Love and Deepest Respect”.
On her death local dignitaries such as Mayor Ethel Ogle and Reeve W. R. Jack remarked on the widespread influence she had on the hundreds of students fortunate enough to have been taught by Miss Casselman.
