Four prominent members of the Harvard community have declared their support for the Cambridge referendum against the Vietnam war.

Former Senator Maurine D. Neuberger (D-Ore.), Head of Radcliffe's South House, said that the vote "cannot help but have an effect on the policy-makers in Washington."

John Kenneth Galbraith, Paul M. Warburg Professor of Economics, and Nobel Prize-winning professors of Biology George Wald and James D. Watson joined Mrs. Neuberger and 180 other Cambridge residents in signing a statement endorsing the referendum.

Mrs. Neuberger urged all citizens who oppose the war to approve the referendum, "even though one may not agree with every word in the text."

Citing the Cambridge appeal and a similar San Francisco referendum as "the first time that all the people have officially been asked to express themselves on the Administration's war policy," she called the vote "the most useful and legitimate way" to oppose the war.

Howard Zinn, professor at Boston University, congratulated the group at a CNCV gathering Friday night. Pointing out the significance of the referendum, Zinn commented "I've been delegated by the world to tell you how important what you are doing is."

The Cambridge Neighborhood Committee on Vietnam, sponsor of the referendum, plans to have 400 volunteers distribute leaflets throughout Cambridge today and tomorrow. On Tuesday the CNCV intends to station poll watchers in every precinct, pass out sample ballots, and provide transportation to the polls.
