A Cultured Quarter

Today we moved into our new home, a nice spacious apartment in Polanco, eight minutes' walk from the office. For the first time the girls have their own separate rooms, end of an era, beginning of another... in A's case, teenagerdom. But we'll be rattling around in it for some time.
One of the many interesting things about Polanco is its street names. Of its 50 or so streets, they're all named after writers and philosophers. So in our immediate neighbourhood we have Aristoteles, Archimedes, Temistoceles and Socrates while a few blocks away are Schiller and Hegel. Over in the west are French writers Moliere, Dumas, Verne and Musset, while lining the south are Byron, Wilde, Shaw and George Elliot. Americans Tennyson, Poe and Emerson fill in some gaps, while Spain is represented by Pedro Calderon de la Barca and  Lope de Vega (where our office is). Oddly there are none named after Mexican writers, but no worries - they're everywhere else (and also 634 Juarez Streets throughout the City).
Actually, there are a few non-writers who are on the map. Isaac Newton cuts a diagonal swathe, while Polanco's broad central avenue is named after Czech president Tomas Garrigue Masaryk, a statue of whom is marooned in a roundabout otherwise taken over by diggers and sewage pipes. 
The only street whose origins I don't know are, ironically, Polanco. Answers on a postcard please.
