Glen Lake Sanatorium
Glen Lake Sanatorium, a tuberculosis treatment center serving Hennepin County in Minnesota, opened on January 4, 1916, with a capacity of 50 patients. In 1909, the Minnesota State Legislature had passed a bill authorizing the appointment of county sanatorium boards and appropriating money for the construction of county sanatoriums. Glen Lake Sanatorium was the fifth of fourteen county sanatoria that opened in Minnesota between 1912 and 1918. The sanatorium had its own post office, and the mailing address was Glen Lake Sanatorium, Oak Terrace, Minnesota, until the surrounding area was incorporated into the City of Minnetonka.
1916: The Glen Lake Sanatorium originally consisted of three stuccoed buildings: A cottage for patients (later known as the East Cottage), an administrative building, and a heating plant/laundry.
1917: A fourth building (known as West Cottage) doubled the capacity.
1921: A eight-floor brick administration building opened and the patient census increased to almost 300.
1922: A detached four-story Children's Building could house up to sixty children—many of whom had been exposed to tuberculosis in their home and had parents undergoing treatment in the main buildings. The building was financed by the Citizens' Aid Society in memory of Lenora Hall Christian.
1924: A building boom greatly expanded the sanatorium campus. An addition housing a bakery and new kitchen linked the 1916 and 1921 administration buildings. A seven-floor East Wing was added and the sanatorium could serve 490 patients. Two residence buildings were constructed. A nurses' residence built north of the main campus also housed other female staff. A power plant and a residence for male employees were built across the road from the campus to the south (present-day Eden Paririe).
1925: The West Wing opened. The capacity was increased to 600. The Christian family funded the Glen Lake Children's Camp on Birch Island Lake, a short distance south of the main sanatorium. It is now on the National Register of Historic Places. 
1934: An addition to the East Wing added surgical suites, occupational and therapy rooms, and classrooms. This building was the second to be financed by the Citizens' Aid Society. Former offices in the other buildings were converted to patient rooms and the final capacity of Glen Lake Sanatorium was 680 patients.
1936: The peak of the tuberculosis epidemic in Hennepin County occurred. The Glen Lake Sanatorium's population exceeded 700, with patients in hallways on gurneys and porches enclosed and transformed into wards. In 1936, the average stay by a patient at Glen Lake was 538 days.
1961: Chemotherapy had all but eliminated the need for extended stays in a sanatorium. Hennepin County leased the Glen Lake Sanatorium campus to the State of Minnesota. The state's Department of Public Welfare converted the sanatorium to a psycho-geriatric nursing home to serve aging residents of its state hospital system.
1990: The state closed the nursing home when the Department of Human Services (formerly DPW) moved to a decentralized system of care.
1993: The entire campus, excepting the children's camp which is located in Eden Prairie, was razed. The Glen Lake Golf and Practice Center operated by Three Rivers Park District now occupies the site.
The Glen Lake Sanatorium was constructed on the Trudeau Sanatorium model, established at the Adirondack Cottage Sanitarium in Saranac Lake, New York by Dr. Edward Livingston Trudeau. The fresh-air-and-bed-rest treatment of tuberculous patients often meant open windows, even during Minnesota winters. Sun therapy, called heliotherapy, was the other essential element of early treatment at Glen Lake. The 1921 Administration building and East and West Wings featured "deck houses" or uncovered porches running the entire length of the buildings' top floors. Patients would lie in beds entirely exposed to the sun's rays, wearing minimal clothing. Patients' rooms on other floors had floor-to-ceiling triple-hung windows that would slide up and allow beds to be wheeled onto small porches.
In 1922, Glen Lake Sanatorium doctors first adopted and performed a surgical procedure known as artificial pneumothorax, which collapsed the lung affected by pulmonary tuberculosis. Collapse inhibited the proliferation of tubercle bacilli and stimulated the formation of scar tissue that controlled the disease. Another method, called extrapleural thoracoplasty, involved removal of portions of several ribs to collapse the chest wall. Phrenic nerve interruption was introduced to Glen Lake in 1924. This paralysis of the diaphragm reduced movement of the affected lung.
The collapse era was followed by chemotherapy. Streptomycin, a World War II development, was readily available by 1949. Isoniazid came into use in 1952 and, together with streptomycin, shortened patient stays from years to months.

The opening black and white sequence of Untamed Heart was filmed at Glen Lake Sanatorium shortly before it was demolished. In the movie, it represented the Catholic orphanage in which Christian Slater's character grew up. The bedside scene was filmed in the Children's Building and the other scene took place in the main first-floor hallway of the Administration Building. At the time of filming, the working title was "Baboon Heart."
