If I had a collaborator working with me on Yorkville memories as talented as John F. Harvey, the fellow who organized the postcard history of Maplewood at the link below, I'd be in research heaven.
The Third Avenue El and my grandfather are on my mind today. Thomas E. Pryor was born on the third floor at 820 Third Avenue on December 15, 1900 while steam engines going up and downtown rattled by the apartment's front windows (a 1940 picture of the block frontage is below). The rail was electrified in 1904 after the IRT came uptown. Thomas belonged to the St. Patrick's parish. He was baptized in the Cathedral and that certificate (below) has his correct birth date and baptismal date.
