Peter Hayward studied at Middleburg College and graduated in 1923. He was a member of the Salmagundi Club, the Honolulu Art Association, Windward Artist's Guild, the Lahaina Art Association and the AAPL. He exhibited in New York in the 1950’s winning the Grand Prize All Media at the Washington Square Outdoor Art Show. His artistic career was divided between Hawai'i, the East Coast, and the many places of the world he visited. He had 14 one-man shows in New York, 5 in Honolulu, and several in Palm Beach, San Francisco, Miami, and Boston.
Hayward preferred oils and bronzes and taught both sculpture and oil painting. Having taught himself to paint following a serious car accident, he mastered the palette knife and combined the spontaneous brushwork and luminous scenes of impressionism with the bold expressive strokes of post impressionism. Hayward has been described to be "like a poet creating magic from ordinary prose, he gives us - not just Hawai'i - but the magic of the island of love."
