It’s International Women’s Day, and today, we’d like to acknowledge just a few of the really sharp women urbanists we rely on.

Too often, sexism, in either its blatant or latent forms rears its ugly head in social media. A couple of weeks back, we read a commentary from an exasperated Lisa Schweitzer, challenging a condescending twitter reply to her reactions of California’s Senate Bill 827. Schweitzer researches and teaches urban planning at the Universty of Southern California, and has a very trenchant blog on urban affairs. (Schweitzer argued that the initial draft of the bill, which would liberalize zoning near transit, would likely need some amendments to minimize windfalls to some property owners). In her view, she was being challenged not so much on the merits of her arguments, but because she was being treated as “a misguided girl speaking when she should be spoken to.” Dr. Schweitzer hardly needs our endorsement of her bonafides in talking seriously about this subject, and the strength of her argument illustrates her depth of knowledge here.

Admittedly, this is only a very truncated list of the women who have smart, relevant things to say about cities. So consider it just a start.
