John Wellborn Root, Jr.
John Wellborn Root, Jr. (1887–1963) was a significant United States architect based in Chicago. He was the son of architect John Wellborn Root. As a young man, he graduated from Cornell University and studied architecture at Paris' École nationale supérieure des Beaux-Arts, where he became friends with John Augur Holabird, the son of another famous Chicago architect. Root returned to the States and joined his friend on the architectural staff at Holabird & Roche in 1919.
After the deaths of William Holabird in 1923 and Martin Roche in 1927, the firm was reorganized under the new partnership of Holabird & Root. They worked on many dazzling projects in the late 1920s and early 1930s, before the Great Depression slowed new construction. These years are notable for the firm's many impressive Art Deco buildings.
The firm weathered the Depression and Root remained an active partner into old age.
