History
Parent Study Group Begins Primary Class
In 1965, a parent study group dedicated to the educational theories of Dr. Maria Montessori came together and hired Montessori trained teachers to begin teaching their children. The new Montessori Primary class has 12 children enrolled and meets at the North Shore Unitarian Church in Lake Forest.

During a parent meeting, Barbara S. Lee, one of MSLF's founding members, stands in the living room of her home on Blodgett Avenue in Lake Bluff.

Foreign Language Program Introduced
A French program is introduced for the Primary children. Written in a February 1969 newsletter: “A French Program is to expose a child in the 3-6 year old group to new sounds and to teach him how to pronounce these sounds correctly. At this young age, the child’s adaptability to new situations, the flexibility of his oral muscles, and his freedom from psychological blocks, all conspire to allow him to repeat with near perfection the sounds he hears.
