Brown University has their portrait collection online! And so finding out about the painting was relatively easy, however unlike most of the portrait collection, there was not a written narrtive of Mr. Appleget, just very basic info. Still, it is wonderful that they have this online resource.
Thomas Baird Appleget was University Vice-President from 1949 - 1959.
Unfortunately, Brown University did not post a color version (I got spoiled by their others). However to learn a little bit more about the painting or person follow this link:
