1914
A popular, public elementary school, the Agassiz School in Cambridge (also known as Miss Baldwin's School), is closed, forcing parents to look for alternatives. When the school closes, the beloved Miss Baldwin, the principal and a preeminent African American educator retires.
1915
Ernest and Agnes Hocking, working in conjunction with Mrs. Wallace Atwood, begin the "Cooperative Open Air School" in the Hocking home at 16 Quincy Street in Cambridge. Classes are held on the back porch with the windows open in all seasons. It is the first independent, coeducational school in the area.
At the school's 80th birthday in 1995, Richard Hocking '19 recounted the names of the school's first students: Margaret Lane, Rosamund Lane, Mary Williams, Franklin Willians, Katherine Sturgis, Wallace Atwood Jr., and Richard himself.
Parents share the teaching of arithmetic, history, geography, poetry, music, French, biology, carpentry, and drawing. In the early days of the school, a Cambridge neighbor, Robert Frost, visits and reads his poetry to the children.
1916
The embryonic school prospers enough that six teachers and a janitor are listed on the payroll. Parents continue to serve as volunteer teachers.
1917
Due to a growing enrollment — there are now 70 students — the school moves to the Charles Eliot Norton Estate ("Shady Hill Square") at the corner of Scott and Holden Streets in Cambridge. At this location, it constructs four "cottage-like" classroom buildings and an assembly hall.
The school hires C. H. Martin to be the principal, but he is drafted into the army before school starts in the fall and Mrs. Hocking is appointed in his place. Lillian Putnam is hired to teach science and stays at the school for 40 years. Tuitions range from $90 for Grade I to $155 for Grades VII and VIII.
1918
Ellen Scott Davidson is hired as principal. The enrollment drops to below 40 students. There are discussions about transferring control of the school to Harvard University's Division of Education to serve as a lab school, but that idea is ultimately rejected.
1919
Miss Davidson resigns because of ill health and is replaced by Miss Cobb as principal.
1920
The Board is asked to provide more heat for the classrooms. "Present conditions are well enough for the children, but too heroic for the teachers, at least on very cold days. A temperature of not less than 30 degrees to 40 degrees is desirable." No action is taken. Miss Cobb resigns. Tuition is $110 for Beginners and $300 for Grade IX. The total budget for salaries is $9,140.
