The Frieda Fromm-Reichmann Cottage is a historic house located at 19 Thomas Street in Rockville, Montgomery County, Maryland.

It was built in 1936 to house the residence and professional office of Frieda Fromm-Reichmann, one of the leading psychoanalysts at the Chestnut Lodge psychiatric hospital, on whose grounds it stood.

[1] The Frieda Fromm-Reichmann Cottage stands in a park-like setting on what were formerly the grounds of Chestnut Lodge, which served as a psychiatric hospital until 1999.

It was built with features to serve Frieda's work "'like a narrow office near the entrance for a secretary-receptionist, and soundproof double doors on the consulting room.

The cabinets on the first floor had special locks to protect their contents from unruly patients, and the front door had an extra device that could be fastened from the inside to deter unexpected 'visitors'.
