Barnett J. (Bud) Brimberg started his first venture when he should have been in class at Tulane Law School. But, instead snuck into the Business School’s inaugural Entrepreneurship course. The course required him to develop a business plan. Brimberg started a company instead (“highly unorthodox” declared the professor) to produce limited-edition posters as a fund-raiser for the then-nascent New Orleans Jazz Festival. Over its 50+ year history the company, now called art4now®, has raised over $35 million for the not-for-profit Foundation that stages the Festival and spawned an industry. The poster series is among the most collected art projects in the world. The American-made BayouWear® clothing line based on art motifs from his posters, inspired by South Louisiana’s culture, was added in 1981 and became a coveted collectible in its own right, which has been documented in global media including the New York Times.

​

Brimberg patented an architectural graphic system and an OTC pharmaceutical based on his inventions selling these ventures to Fortune 500 and NASDAQ-listed companies, respectively. He has served as a strategic advisor to public and private firms. He was managing director of Trident Audio Developments, Shepperton, England, turning around this manufacturer of professional recording studio equipment. He is a member of the Louisiana and California bars.

 

His interest in architecture and design became a lifetime hobby, building and designing all of his personal residences. Of all his successes, he considers his two sons his greatest achievements.
