In the second part of the Bowery Boys' Bronx Trilogy -- recounting the entire history of New York City's northernmost borough -- we focus on the years between 1875 and 1945, a time of great evolution and growth for the former pastoral areas of Westchester County. New York considered the newly annexed region to be of great service to the over-crowded city in Manhattan, a blank canvas for visionary urban planners.  Soon great parks and mass transit transformed these northern areas of New York into a sibling (or, perhaps more accurately, a step-child) of the densely packed city to the south. The Grand Concourse embodied the promise of a new life for thousands of new residents -- mostly first and second-generation immigrants, many of them Jewish newcomers. But the first time that many outside New York became aware of the Bronx may have been the arrival in 1923 of New York's most victorious baseball team, arriving via a spectacular new stadium where sports history would frequently be made. By the 1930s Parks Commissioner Robert Moses began looking at the borough as a major factor in his grand urban development plans. In some cases, this involved the creation of vital public recreations (like Orchard Beach). Other decisions would mark the beginning of new troubles for the Bronx.
