In 1967 hundreds of students at Boston University petitioned Baird to challenge a Massachusetts law that prohibited providing contraception to unmarried persons. On April 6, 1967, he gave a lecture at Boston University, during which he gave a condom and a package of over-the-counter contraceptive foam to a female college student. He was immediately arrested and eventually jailed. His appeal of his conviction culminated in the 1972 Supreme Court decision "Eisenstadt v. Baird", which established the right of unmarried persons to possess contraception on the same basis as married couples. U.S. Supreme Court Justice William J. Brennan, Jr. wrote in that decision: "If the right of privacy means anything, it is the right of the individual to be free from unwarranted governmental intrusion into matters so fundamentally affecting a person as to whether to bear or beget a child." "Eisenstadt v. Baird" has been described as "among the most influential in the United States during the entire century by any manner or means of measurement".
