On January 16, 1786, Virginia enacted the Statute for Religious Freedom authored by Thomas Jefferson.
The day is also noted in the title of Ayn Rand’s hit play, Night of January 16th. First performed in 1934 as Woman on Trial, it continued on over the next few years under the title with which it is now famous, and (with the addition of the definite article before “Night”) under which it was filmed in 1941.
