Louis Dorfsman (April 24, 1918 – October 22, 2008) was an American graphic designer who oversaw almost every aspect of the advertising and corporate identity for the Columbia Broadcasting System (CBS) in his 40 years with the network.

Dorfsman's designs were described by The New York Times as featuring "clear typography, simple slogans and smart illustration".

The Times credited the "cleverness and subtle beauty of his advertisements" with drawing viewers to the network's news and entertainment programs.

[2] Dorfsman oversaw design of annual reports for CBS and created promotional commemorative volumes, including a 1969 limited-edition book with a cover embossed to resemble the lunar surface, after the first crewed Moon landing.

The responsibilities for advertising, which had previously been handled in-house under Dorfsman's supervision, were transferred to Backer, Spielvogel, Bates.

[2] In 1978, Dorfsman was recognized as a medalist by the AIGA, "awarded to individuals in recognition of their exceptional achievements, services or other contributions to the field of design and visual communication".
