Graham met her first husband
Gene Zion at
Condé Nast. They were married in July 1948. Zion was urged by Graham and his editor,
Ursula Nordstrom of
Harper and Brothers, to write children's books. He has said that it was Graham’s sketch of children gathering apples in an orchard, done several years earlier in Canada, that inspired his first book,
All Falling Down (1951). The husband-and-wife team became famous for the
Harry series of books, beginning with
Harry the Dirty Dog (1956) and followed by
No Roses for Harry! (1958),
Harry and the Lady Next Door (1960) and
Harry By the Sea (1965). The collaboration ended with their divorce in 1968. Graham received two
Caldecott Medals, one for her work on
All Falling Down and the second for her work on
The Storm Book. Graham launched her own writing career around the time of the divorce with
Be Nice to Spiders (1967). She later developed her own canine hero, Benjy, through a series of books. ==Later life==
