Ten miles up the mainline from Philadelphia is Lower Marion Township. Driving up route 30 rowhouses give way to stone houses and trees. I pass St. Joe’s, the French International School, then after Haverford I take a right. There not quite all the way to Rosemont or Villanova, is Bryn Mawr.Quakers founded the school in 1885 but the board soon decided the institution would have no religious affiliation. It is the first school in America to offer a PhD to women.Bryn Mawr is one of the seven sisters. It brings to mind images of knee high socks and plaid skirts I saw none of that when I visited. I did see a chemistry lab filled with glass tubes and DNA models.
