This window was given in memory of Sarah Jane Houghton, wife of Trustee William S. Houghton, by her children Clement and Elizabeth Houghton and placed in the chapel in 1908. The work is meant as an illustration of the hymn 'Glory be to God on high, and peace on earth, good will to all.' The text reads 'Gloria in excelsis Deo.' The window was designed by Frederick Wilson and created by Tiffany Studios.
