An estimated 200 residents filed into the Lamb Room at New Canaan Library on Monday night for a presentation led by NewCanaanite.com contributing editor Terry Dinan, on New Canaan in 1927. New Canaan Library’s selection of “One Summer: America 1927” for a community-wide reading initiative will culminate this week with Wednesday’s speakeasy in the same Lamb Room and Saturday’s original play at the Powerhouse Theater. Terry, who writes the news site’s popular “0684-Old” local history feature, walked the crowd through a rapidly changing time in New Canaan’s history. The 1920’s saw New Canaan’s population jump by 40 percent, and important pieces of the town’s downtown and landscape took shape in the period. In 1927 itself, both Karl Chevrolet and New Canaan High School were founded, and the town marked locally much of what Bryson chronicled in his book, including Babe Ruth’s 60-home run feat and Charles Lindbergh’s trans-Atlantic flight.
