as an architect before leaving Keeseville. Isaac Perry's architectural work in Keeseville is not well documented, but it is likely that the Emma Peale residence, called "Rembrandt Hall" (1851), a Gothic Revival style Downingesque cottage that contains a spiral staircase by the Perrys, is an early design. By 1852, Perry relocated to New York to apprentice in the office of architect Thomas R. Jackson (1826-1901). Jackson, a native of England who migrated to the United States as a child, had risen to the position of head draftsman in the office of Richard Upjohn (1802-1872), one of New York's most prominent designers. The nature of his work with Jackson and the projects in which he collaborated, are not known.
The inebriate asylum marked the turning point in Perry's architectural career. Perry's inexperience is evident in Turner's account of the building's design.
Perry later recalled that he penciled the plans with the assistance of his wife, Lucretia Gibson Perry. He also appears to have been assisted by Peter Bonnett Wight (1838-1925), the head draftsman in Jackson's firm, but Wight's role in the project is not well documented.
