How did John Wellborn Root’s death affect the planning of the 1893 World’s Columbian Exposition?

The sudden death of John Wellborn Root in January 1891 significantly altered the leadership structure for the World’s Columbian Exposition of 1893.12

Prior to his passing, Root and his partner Daniel Burnham had been appointed as the fair's consulting architects. Following Root's death, Burnham resigned from that specific role to assume the position of head of construction. This transition placed the full responsibility for the massive project—which involved overseeing the construction of approximately 150 buildings across more than 600 acres—squarely on Burnham’s shoulders.1

Despite the loss of his partner, who had been the firm's primary designer, Burnham successfully led a workforce of 10,000 men to complete the fair’s infrastructure and grand Neoclassical buildings in just over two years.13
