Dorothy Lake Gregory was born in Brooklyn, NY and showed artistic talent early in life. She enrolled at the Pratt Institute in New York and studied at the Art Student League with Robert Henri. It was there that she would meet her future husband, Ross Moffett.  At the urging of a fellow student, Gregory went to Provincetown in 1914 to study with Charles Hawthorne. It was there that her relationship with Moffett developed; their marriage lasted for almost 51 years.   Her art expressed a tremendous range of styles and mediums. In spite of her success as an illustrator (she did over 20 books and many magazines), she readily sacrificed her own career to care for her family and promote the artwork of her husband.
