NEW YORK - Lou Dorfsman, who for more than 40 years designed every aspect of the Columbia Broadcasting System's advertising and corporate identity, including the set of Walter Cronkite's newsroom and the typographically elegant sign system for CBS's New York headquarters, known as Black Rock, died Wednesday in Roslyn, N.Y. He was 90.

The cause was congestive heart failure, said his daughter, Elissa Dorfsman.

Mr. Dorfsman's work became a model for corporate communications, in the marketing discipline now called branding. In 1946, when he joined CBS as art director for its successful radio networks, the company was already a leader in both advertising and the relatively new field of corporate identity. Frank Stanton, then CBS president, understood the business value of sophisticated design and had earlier hired William Golden as the overall art director; in 1951, Golden designed the emblematic CBS eye, among the most identifiable logos in the world.

Mr. Dorfsman not only extended Golden's aesthetic by combining conceptual clarity and provocative visual presentation, but developed his own signature style of graphic design.

Unlike so many product advertisements created by Madison Avenue, which in the 1940s and '50s were visually mundane and text-heavy, Mr. Dorfsman's designs featured clear typography, simple slogans, and smart illustration. He also commissioned work from Feliks Topolski, a portraitist, and the printmaker and painter Ben Shahn, though Shahn was then under scrutiny by the House Un-American Activities Committee for his affiliation with leftist groups and causes.

After Golden's sudden death in 1959 at 48, Mr. Dorfsman was named creative director of CBS television, and in 1964 he became the director of design for the entire Columbia Broadcasting System. A few years later his title became senior vice president and creative director for marketing communications and design. He maintained tight creative control, which ensured design continuity from the CBS logo to its proprietary typeface, called CBS Didot. The cleverness and subtle beauty of his advertisements were credited with winning over many viewers to both news and entertainment programs on the network.

"He was the kingpin of the New York school of design, a pluperfect, fearless, uncompromising perfectionist, and a father of corporate image in the world," said George Lois, one of the leaders of advertising's "creative revolution," who also worked at CBS in the early '50s and who regarded Mr. Dorfsman as a mentor.

Louis Dorfsman was born in 1918 on the Lower East Side of Manhattan; a few years later, his father, Samuel Dorfsman, a sign painter, and his mother, Molly, both immigrants from Poland, moved the family to the Bronx. After graduating from Roosevelt High School in 1935, the younger Mr. Dorfsman wanted to study bacteriology at New York University but could not afford the $300 tuition. Instead he was accepted at Cooper Union, where tuition was free and art and design courses were plentiful. He graduated in 1939 and remained connected to the school, serving on its board of directors for many years.
