Weaver head of the Department of Housing and Urban Development (HUD), the agency that develops and implements national housing policy and enforces fair housing laws.

As many of the country’s African Americans lived in run-down inner-city areas, appointing Weaver was an attempt to show his African American constituency that he meant business on both counts.

More specifically, it is linked with the music of the late-'60s counterculture and antiwar movement. But opposition to the war was far from widespread back in 1966—a fact that was reflected not just in popular opinion polls, but in the pop charts, too.

Pope Paul VI addresses 150,000 people in St. Peter’s Square in Rome and calls for an end to the war in Vietnam through negotiations.

But he had chronic arthritis in his pitching arm, and he was afraid that if he kept playing baseball, eventually he wouldn’t be able to use his left hand at all. “In those days there was no surgery,” he said much later. “The wisdom was if you went in there, it would only make things worse and your career would be over, anyway. Now you go in, fix it, and you’re OK for next spring.”
