Stanford White
Stanford White (November 9, 1853 – June 25, 1906) was an American architect. He was also a partner in the architectural firm McKim, Mead & White, one of the most significant Beaux-Arts firms. He designed many houses for the rich, in addition to numerous civic, institutional, and religious buildings. His temporary Washington Square Arch was so popular that he was commissioned to design a permanent one. His design principles embodied the "American Renaissance".
In 1906, White was shot and killed at the Madison Square Theatre by Harry Kendall Thaw, in front of a large audience. https://en.wikipedia.org/wiki/Stanford_White
“Stanford White was a champion frame designer. For adaptation of classical elements into new works of art, White’s frames remain unsurpassed. He embraced, experimented, and transformed traditional patterns. Architectonic tabernacle styles, frames with pierced foliate and arabesque patterns, basket weaves, fish-scales, twining leaves, and fence-like grilles with different tonalities of gold and metal leaf were specifically created to harmonize with each individual painting.” — fig. 5, p 143, excerpt from “American Period Frame Connoisseurship in the Twenty-first Century,” extensive chapter written by Tracy Gill and Simeon Lagodich, contributing authors, American Art Collecting and Connoisseurship, Merrell Publishers Limited, London and New York, Sept 2020.
“During his lifetime, Stanford White closely guarded permissions for fabrication of his frame designs. Following his untimely death in 1906, the Newcomb-Macklin Company of New York and Chicago acquired the molds and rights to reproduce White’s frame designs and began making copies under its own name in 1912. … A selection of these designs can be seen in photographic plates of grouped frame corners, presented in a book on his father’s work by Lawrence Grant White, Sketches and Designs by Stanford White, New York: Architectural Book Publishing 1920.” —excerpt from Beaux Arts & Crafts: Masterpieces of American Frame Design 1890–1920, p. 16, High Museum of Art exhibition catalogue written by Tracy Gill.
