Harold Ainsworth Peto was originally trained as an architect, but made his reputation as a garden designer in the late-19th and early-20th centuries. Born in 1854, the eighth child of Sir Samuel Morton Peto, he was educated in England at Harrow and qualified as an architect in 1871.
For 21 years he worked in partnership with Ernest George in London, England. In 1892 he left the partnership and began his career in garden and interior design. Much of his work was in the Italiantate style, influenced by his frequent trips to Italy.
