This resulted in the book Influentials in Two Border Cities (1965). Concurrently, a grant from the Rockefeller Foundation led to a Symposium at Notre Dame and publication of the book, Religion, Revolution and Reform: New Forces for Change in Latin America (1964). Another area of D'Antonio's research was on the topic of Birth Control and the Catholic Church. Research grants from The Carnegie Corporation, the Department of Health, Education and Welfare (HEW), and The Rockefeller Foundation, allowed him to examine the role of the Catholic Church at a time when birth control, public policy and a woman's right to choose had become prevalent political issues. In the 1960s the Vatican, Pope Paul VI, and most church officials in America did not embrace academic research that was contrary to current church policy. D'Antonio's research provided substantial data that supported changes in public attitudes and policy. Beginning in the fall of 1963, and extending to 1968, Notre Dame created a Committee on "Population and Responsible Parenthood", which included Social Scientists, Medical Doctors, Philosophers, Theologians, and Lawyers, all working informally with the Papal Birth Control Commission. The objective was to determine whether it was possible to change the Church's current position (that was against contraceptive birth control.) In the summer of 1965 the Commission recommended amending their policy to be more aligned with the opinions and beliefs of American Catholics. D'Antonio was asked to organize the Catholic Committee on Population and Government Policy. This national group consisted of faculty from 57 Catholic colleges, clergy, nuns, lawyers and physicians, all of whom supported government family planning programs. Father Dexter Hanley, a Georgetown University Law Professor, prepared a legal brief showing that it would be ethically possible for the government to provide funds for family planning, as long as all methods of family planning were offered and that there was no coercion or pressure against moral choice. Some 517 Catholics, including four Law School Deans and several Medical School leaders signed in support. On May 10, 1966, D'Antonio, as chairman, testified before the Senate Committee on Labor and Public Welfare in Washington, stating, "in a pluralistic society, some legislation may be desirable even though it may not be in accord with the moral principles of a minority of the society's members." On May 11, 1966, The New York Times published an article citing a Gallup poll showing that 59 per cent of the nation's Roman
