Legal career[edit]

It was under the leadership of District Attorney Frank Hogan where Tanenbaum learned about trial preparedness and presenting evidence to a jury as an Assistant New York County District Attorney in Manhattan. Later, Tanenbaum became head of the Homicide Bureau, served as Chief of the Criminal Courts, and was in charge of the D.A.'s legal staff training program. During his time in the D.A.'s office, Robert K. Tanenbaum never lost a felony case.[2]

After his tenure in Manhattan's D.A.'s office, Robert K. Tanenbaum served as Deputy Chief Counsel for the House Select Committee on Assassinations to investigate the John F. Kennedy assassination and the Martin Luther King, Jr. assassination. Tanenbaum subsequently resigned from the post shortly after being named.[3] In 1988 he appeared in the documentary The Men Who Killed Kennedy.

In private practice, notably, he was a special prosecution consultant on the Hillside Strangler case in Los Angeles; defended Amy Grossberg in her sensationalized baby death case; and represented eight black plaintiffs in a significant racial profiling case.[4]

He taught Advanced Criminal Procedure for four years at Boalt Hall School of Law at the University of California, Berkeley.

His cousin Michael Gruber[8] was the ghostwriter of the first part of the popular Butch Karp -Marlene Ciampi series of novels, starting with No Lesser Plea and ending with Resolved.[9] After the partnership with Tanenbaum ended, Gruber began publishing novels using his own name.[10]

Tanenbaum's The Piano Teacher , co-written with Peter S.
