Summers’ mom is top economist, has baffling ability to overcome “innate” math barrier

I guess Lawrence Summers’ mom is an exception to his chicks-are-naturally-bad-at-math rule.
Here’s a 2001 bio from when she was Ombudsman at the University of Pennsylvania:
Anita Summers, PhD joined the University of Pennsylvania in l979 as an Adjunct Professor at Wharton, became a Professor of Public Policy and Management in 1982, and chaired that department from 1983-1988. She was a member of Provost’s Academic Planning and Budget Committee from l984-1990, in addition to many other University activities. Dr. Summers has been a recipient of the Excellence in Teaching Awards at Wharton several times. While technically retired, her expertise is very much sought after as she is considered a leading authority on urban economic development and finance and educational efficiency. She is also a senior research fellow at Wharton’s Samuel Zell and Robert Lurie Real Estate Center.
Pretty impressive—for a girl that is.
Anita: You know, he’s not too old for a good spanking.
