Over 160 years of excellence.
Our history at-a-glance.
William Greenleaf Eliot, a prominent Unitarian minister in St. Louis and educational pioneer who co-founded Washington University in St. Louis in 1853, established a school for girls in 1859: Mary Institute was named for his daughter, Mary Rhodes Eliot, who died at age 16.
From the start, the School prospered. In 1928, an alumna donated 22 acres, Washington University added 18 more, and Mary Institute soon had a new campus in the country at Ladue and Warson Roads.
Shortly before Mary Institute’s founding, Washington University established an „academic sub-department“ for boys. In 1879, it was named „Smith Academy“ and began operating in downtown St. Louis with an enrollment that eventually grew to 385. By the second decade of the 1900s, Smith Academy’s fortunes had declined due to growing competition and the diminished importance of the school’s intended role as a feeder for Washington University. Recognizing Smith’s situation, a group of local community leaders met to discuss the „country day school“ movement of relocating schools away from congested cities to foster high academic standards and discipline in a healthier rural setting. These discussions led to the opening of St. Louis Country Day School in 1917, a few months after Smith Academy closed its doors. Country Day, teaching grades 5-12, occupied a 55-acre campus in north St. Louis County, near the municipal airport, until late 1957, when airport expansion prompted relocation to a large parcel of land adjacent to Mary Institute.
Program coordination between the two schools evolved over the years, and in 1992, a full-scale merger was approved, creating a single school – Mary Institute and Saint Louis Country Day School (MICDS) – with one board, administration, faculty, student body, and common curriculum.
Today, MICDS is considered one of the nation’s pre-eminent independent schools, and it is continuing to shape a new generation of stellar graduates and world leaders.
Make history with us.

At Eliot’s request, the incorporators of Eliot Seminary change the name to Washington Institute (later Washington University).
Mary Rhodes Eliot, 16, first-born daughter of William Greenleaf Eliot, dies after a sudden illness. In his grief, Eliot pens a collection of sermons, The Discipline of Sorrow.

Eliot and others on the Board of Trustees prompt Washington University to found a “Female Department” to prepare local girls for university. In honor of Eliot’s critical early leadership, the University insists that it be named for his daughter.
September 20: Mary Institute opens on Lucas Place with six teachers. Curriculum includes English, physiology/natural history, vocal/instrumental music, drawing, calisthenics, and French. Optional courses include higher mathematics and natural sciences at nearby Washington University.
Margaret Dawes Eliot, mother of William Greenleaf Eliot, donates $1,000 to the new school bearing her granddaughter’s name. She stipulates that “the scholars” henceforth be given an annual holiday “on or near the 11th of May for a May Festival.” Known since as M. D. Eliot “Grandmother’s“ Day, it continues to be enjoyed by MICDS students and is the School’s longest-standing tradition.
Calvin Pennell, nephew and former ward of educator and statesman Horace Mann, is named Principal. Pennell infuses the School with groundbreaking “whole child” educational theories developed by his uncle.
First Mary Institute commencement exercises. Seven students graduate.
Eliot is named the third Chancellor of Washington University, a post he holds until his death in 1887.

Mary Institute moves to new Locust Street facility; 300 students are enrolled.
Harvard graduate Edmund Sears is named Mary Institute’s fourth Principal.

THE COUNTRY DAY SCHOOL MOVEMENT:
At the turn of the 20th century, urban overcrowding, pollution, crime, and vice are facts of life. Families across the United States begin favoring educational options for their children that remove them from such seemingly unhealthy environments during the academic day.
St. Louis civic leaders invite Charles Bovey, trustee of the Blake School in Minneapolis, to visit and share information about the country day school approach to education.
Spring: Smith Academy closes after 61 years because of declining enrollment, disciplinary problems, and parent dissatisfaction with its “classical” curriculum.
May 11: Several prominent St. Louis families – some formerly involved with Smith Academy, some not – file incorporation papers establishing St. Louis Country Day School.

Decades later, Walker’s grandson and great-grandson will be elected the 41st and 43rd Presidents of the United States, George Herbert Walker Bush and George W. Bush.
Summer: Country Day trustees lease the Julius Walsh estate on Brown Road in north St. Louis County. The rural site is easily accessed by a streetcar line from the city. The Walsh mansion becomes classrooms; the stables and carriage house are transformed into a gymnasium and locker room; a horse track serves athletic needs. The School purchases the property in 1918.
September 29: Country Day opens with 45 students. Enrollment grows to 52 this first year, including 30 previous Smith Academy students. Two former Smith instructors are among the five faculty members present on the first day.
From 1917 until the mid-1930s, a daily streetcar service ferries Country Day boys from their city neighborhoods to the north county campus. Affectionately known as “The Special,” the trolley is chartered for exclusive use by the School. School “masters” are assigned the unenviable roles of supervisors, as hijinks and horseplay (and last-minute cramming) characterize each 50-minute trip to and from campus.
Country Day chooses red and white as its school colors. Boys are divided into “Red” and “White” teams for athletic competitions, a tradition that continues for the Lower and Middle Schools into the 1960s.
Moved by the devastations of World War I, Mary Institute girls stage concerts and pantomimes to benefit European relief efforts. Country Day boys sell Liberty Bonds and plant “thrift gardens” on campus.

Mary Institute alumna Sarah Glasgow Wilson (1876) donates $500,000 and 22 acres of land at the corner of Warson and Ladue Roads to build a country day school campus. Adjusted for inflation, Wilson’s gift would top $9 million today.
The ABC League is founded for boys’ interscholastic sports. Its first event is a track meet involving Country Day, Western Military Academy, John Burroughs, and Principia.
A small plane makes an emergency landing on Country Day’s Lower School football field. Delighted boys swarm around the craft, excitedly questioning the pilot — but it is, perhaps, a harbinger of things to come, as the St. Louis airport, originally a mile to the southwest, inches ever closer to the Brown Road campus.
The fourth and final Mary Institute campus opens; replete with tennis courts and hockey fields, it reflects the School’s long-standing commitment to healthy minds and bodies.
