This week’s show dusts off two classic stories about times in Boston history when women’s volunteer organizations had a big impact on Boston. First, we’ll talk about the Massachusetts Emergency and Hygiene Association, whose members introduced the concept of a playground to the American public in late 19th century Boston. Then, we’ll fast forward a few decades to the 19 – teens, when the Women’ Municipal League sponsored Boston’s first (and so far only ) Rat Day. Both of these projects made valuable contributions to Boston’s quality of life, and they happened at a time when society didn’t generally approve of women’s work outside the home.
