Alexander Richardson Grant, the namesake of the firm, began his
accounting career at Ernst & Ernst (a predecessor of Ernst
& Young) but, at the tender age of 26, decided it was time to
be his own boss. Alexander Grant & Co. opened in Chicago in
1924 with a mission to provide accounting services to middle-market
companies. Grant died suddenly in 1938, but his firm continued to
grow. By 1961, net revenue exceeded $5 million, and in the late
1960s, Alexander Grant & Co. joined with firms in Australia,
Canada, and the U.K. to establish Alexander Grant Tansley Witt,
which operated internationally for 10 years. Grant Thornton
International was born in 1980 when Grant and 49 other
international accounting firms formed a global organization; by
1985, Alexander Grant & Co. was ranked the ninth-largest
accounting firm in the U.S. It changed its name to Grant
Thornton in 1986, a reflection of its affiliation with the U.K.
firm Thornton Baker (which also changed its name).
Today, Grant Thornton LLP employs more than 6,400 people and is
the sixth-largest accounting firm in the U.S., according to
Accounting Today's latest rankings by revenue.
