The term Benign Senescent Forgetfulness, introduced in 1958 by V. A. Kral, constitutes the origin of the concept of Mild Cognitive Impairment (MCI), a widely studied but controversial entity. The ambiguities surrounding MCI warrant a re-assessment of its historical origin. Any attempt at an in-depth investigation of Kral's works on that subject should begin with a description of the patient population and professional arena in the Montreal Hebrew Old People's and Sheltering Home, where Kral was a consultant. Based on archival and published sources, I describe the Home's facilities, population, staff and programmes/services, followed by an overview of the dynamic factors inducing a re-examination of its mode of operation in the mid-1950s when Kral joined the Home's professional staff as a consultant.
