article in the April 1930 issue of Western Architect, the high profile of the Carbide & Carbon Building project allowed the Burnham Brothers to secure a commission for the Cuneo Building, another proposed skyscraper of contrasting colors that was planned for the northeast corner of Michigan Avenue and Randolph Street in mid-1929 and was intended to be 657 feet or 60 stories tall. However, the Stock Market Crash of October 1929, followed by the Great Depression, forced cancellation of the Cuneo Building proposal along with many other architectural projects. Thus, the Carbide & Carbon Building was the practice's last major commission before the Great Depression ended, by which time the firm had become Burnham & Hammond. The architects Burnham Brothers was the firm of Daniel H. Jr. and Hubert Burnham, sons of prominent Chicago architect Daniel Burnham, and one of the two successor firms to his D.H. Burnham & Company. After Burnham senior died in 1912, D.H. Burnham & Co. became Graham, Burnham & Co., named after Burnham's main partner, Ernest Graham, and Burnham's two sons. When the two brothers left in 1917 to start their own firm, the remaining members of Graham, Burnham & Co. formed Graham, Anderson, Probst & White – the main successor firm, which carried on Daniel Burnham's remaining work and went on to become one of the major architectural firms in Chicago during the 1920s through the 1940s. The brothers at first confused matters by reviving the name D.H. Burnham Co. (nearly but not exactly like the original D.H. Burnham & Co.), which they maintained for 11 years until 1928, when the firm officially became Burnham Brothers. In 1933, the firm joined with C. Herrick Hammond to form Burnham & Hammond. For all its success over nine decades, GAP&W – which had its offices in Burnham's Railway Exchange Building, where D.H. Burnham & Co. had maintained its offices – had no successor firm (it closed in 2006). The largest architectural firm in Chicago today and one of the major architectural firms worldwide – the world-renowned Skidmore, Owings & Merrill, aka SOM, which also has its headquarters in the Railway Exchange Building – is actually an offshoot of Burnham Brothers: Nathaniel A. Owings joined the practice in 1929 and left in 1934, and Louis Skidmore joined in 1930 and left in 1936. Skidmore and Owings started their own firm in 1936, and John Ogden Merrill joined
