According to her Wikipedia page (http://en.wikipedia.org/wiki/Molly_Yard), she moved to Pittsburgh in 1953, worked on David L. Lawrence's gubernatorial campaign in 1958, led the Western Pennsylvania presidential campaigns of John F. Kennedy in 1960 and George McGovern in 1972, and led an unsuccessful campaign to get NAACP President Byrd Brown the Democratic nomination to Congress.
In 1964 she made an unsuccessful run for the state legislature as a candidate from the 14th Ward. The club formed around her campaign.
Less well-known is that Yard apparently stepped down as president and quit the club in 1977 when she lost a race for ward chair following that year's tumultuous mayoral election.
In a letter to club members announcing her resignation, Yard addressed an ongoing philosophical debate about the club's mission:

Perhaps not coincidentally, Yard joined NOW's national staff the year after writing the letter, so she might have taken the occasion to make a dramatic exit. Still, it's good reading and raises an issues that remain relevant for the club today.
