Lemberg Succeeds Smith at Digitas

BOSTON–Thomas Lemberg has joined relationship marketing agency Digitas as executive vice president, general counsel and secretary, succeeding Marschall Smith, who is leaving the company.

Lemberg, 55, most recently was managing director and general counsel of Cambridge Incubator, where he helped concoct strategies for start-up companies in the wireless technology arena. He has also held senior positions, including general counsel, at Polaroid.

Smith — who came to Boston-based Digitas in late-1999 as the agency was preparing for its initial public offering — is joining boating equipment maker Brunswick in Lake Forest, Ill., as general counsel. He will remain with Digitas for a few weeks to help bring Lemberg up to speed, a Digitas representative said.

Smith joined Digitas from Chicago’s IMC Global, a publicly traded mining and chemical conglomerate, and he was touted as an “acquisitions specialist” who would held Digitas expand its reach worldwide. The agency has, since his arrival, increased its presence in key domestic markets such as New York and San Francisco, and grown in both London and Hong Kong, though it has not made any acquisitions.

Digitas has of late been in talks with the Interpublic Group of Cos. about a possible alliance or buyout, though in recent weeks those talks have significantly cooled, sources said. Smith did not return calls.
