One of Gilder's best known friendships was with illustrator Mary Hallock Foote. Though from very different social circles, and socioeconomic backgrounds, the two became close friends while they were students, and shared a lengthy correspondence throughout their lives.[4] Gilder and Foote had large impacts on each other's careers as they both provided each other with critiques and feedback on their work, and Gilder's husband offered Foote several artistic commissions for his magazine.[4] It was also through the Gilders that Foote was introduced to several other female artists and publishers at the time.[citation needed]
