For those of you who had family in Brooklyn, New York, who lived there between 1924 and 1987, the Museum has a searchable database of more than 46,000 names of graduating Seniors, encompassing more than seventy graduating classes (they graduated two classes a year, in January and June).
You can search by name, school year, even by home address (at least for half of the students).
This is a useful genealogical tool, not to mention and educative one, as one can also browse any of the yearbooks from cover to cover--a virtual "time capsule."
Today another six hundred names have been added, from the graduating class of January 1946.
