Along with her husband, Mrs. Webster spent much of her life and fortune combing auction catalogs and antiquarian shops to create a collection of early scientific instruments so renowned, it is considered in the same company as the Museum of the History of Science at Oxford University and the National Maritime Museum in Greenwich, England, according to Bolt, Adler planetarium vice president for collections.  The Websters are primarily responsible for the world-class collection of scientific instruments at the Adler.

NASS is supporting the Adler to catalog their sundial collection enhanced over the years by Marjorie Kelly and her husband.
