The Show Nelson Rockefeller Kept Calling About
Marshack worked on Rockefeller's vice-presidential staff, in Washington, D.C., for two years. There was speculation in the press regarding the nature of the relationship between Rockefeller and Marshack. For example, long-time Rockefeller aide Joseph E. Persico claimed in the PBS documentary about the Rockefeller family, "It became known that he had been alone with a young woman who worked for him, in undeniably intimate circumstances, and in the course of that evening had died from a heart attack." News organizations widely reported that Marshack was a named beneficiary in his will, though the bulk of his estate was left to his wife with other large gifts going to museums.
Prior to her employment with Rockefeller, she was a radio news reporter for the Associated Press.
In 1992, it was reported that she was still living in New York working as a news writer for WCBS-TV, but the Washington Post noted she declined to comment, saying "I don't do interviews." According to newspapers in September 1994, she was a news writer and producer at WCBS-TV. In December 2008 Parade reported that Marshack married a journalist and was living in Southern California.
