In his career after the fair, Burnham became one of the country's most prominent advocates for the Beaux-Arts movement, as well as the revival of Neo-classical architecture which the fair set off.
Much of Burhham's work was based on the classical style of Greece and Rome.
In his 1924 autobiography, Louis Sullivan, one of the leading architects of the Chicago School, but one who had a difficult relationship with Burnham over an extended period of time, criticized Burnham for what Sullivan viewed as his lack of original expression and dependence on classicism.
Sullivan went on to claim that "the damage wrought by the World's Fair will last for half a century from its date, if not longer" – a sentiment edged with bitterness, as corporate America of the early 20th century had demonstrated a strong preference for Burnham's architectural style over Sullivan's.

Burnham is famously quoted as saying, "Make no little plans.
They have no magic to stir men's blood and probably will not themselves be realized."
This slogan has been taken to capture the essence of Burnham's spirit.

A man of influence, Burnham was considered the pre-eminent architect in America at the start of the 20th century.
He held many positions during his lifetime, including the presidency of the American Institute of Architects.
Other notable architects began their careers under his aegis, such as Joseph W. McCarthy.
Several of his descendants have worked as influential architects and planners in the United States, including his son, Daniel Burnham Jr., and grandchildren Burnham Kelly and Margaret Burnham Geddes.
