Christopher Gray will be on WNYC's Leonard Lopate Show today at noon. Gray has been digging up dirt on the history of New York's urban landscape for 20 years in his "Streetscapes" column in The New York Times.

On the show today, he'll address The Past Lives of Buildings. And, in preparation for the show, listeners have been asked to submit photos of buildings whose histories they've always wanted to know.

Tune in today to hear Gray fill us in on the most intriguing buildings. (thanks for the tip, Jennifer.)
