This window is in memory of Mary Bucklin Claflin, Wellesley's first female Trustee, who served from from 1873 until her death in 1896. It was given by her husband William Claflin, the former Governor of Massachusetts, who signed the charter for the College and served as Trustee from 1873 until his death in 1905. The window is thought to have been created by Frederick Wilson, a stained glass designer at Tiffany. It was placed in the Chapel in 1898, and represents St. Elizabeth teaching St. John the Baptist.
