Painter and decorator Peter C. Grierson was born in Scotland in 1864 to Peter and Anna Grierson. Along with his parents and two siblings, Grierson immigrated to the United States in 1867. In the 1880 Federal Census, Grierson is listed as living in Hartford, Connecticut with his parents and five siblings. The 1880 Census records Greirson as an apprentice to an architect and five years later, the 1885 Hartford City Directory lists him as a practicing architect. After 1886, however, Greirson is listed in the Hartford City Directory as a painter and decorator. Experiencing success as a decorator, Grierson was able to establish his own business and the 1897 Hartford City Directory contains an advertisement for P.C. Grierson & Co., Practical Decorators and Designers. According to the advertisement, the company specialized in "Fresco and Plain Painting. Paper Hanging and Wood Finishes. Relief Work and High-Class Decorating."
A member of the Brotherhood of Painters and Decorators of America, Grierson's archive details that a large part of his business was dependant on the production of stencils for furniture. Samples of stenciled surfaces detail that Grierson worked primarily in the tradition of Hitchcock Chairs. Manufactured in Connecticut, Hitchcock Chairs were an example of early-American massed produced furniture. The chairs were often pieced together using rosewood and then painted black. The black paint was then coated with a binder such as varnish and turpentine. When dry, a stencil was laid flat on the surface and metallic powders were brushed on with small velvet or leather pads. The stencils were traditionally cut into compositions of bowls of fruit, clusters of flowers, and borders of flowering stems, roses, acorns and laurel leaves. Working in the early twentieth-century, Grierson's role in the resurgence of the Hitchcock Chair aesthetic was part of a larger nationalistic colonial-revival movement in the United States.
In 1892 Greirson was married to woman of Irish decent named Mary, with whom he had four children. Grierson died on the 13th of August in 1949 in Hartford.
