By 1833, Sumner, with partners Steven White and Francis J. Oliver, had bought up the half of Noddle's land. Together they founded the East Boston Company, and consolidated additional landholdings. By the year's end, the East Boston Company had complete control over the entire Island. The company's purpose was to own and develop the land and call it East Boston. In anticipation of population growth, the proprietors adopted a grid street plan, the first planned neighborhood in the city of Boston. Jeffries Point, located at the southern end of the peninsula that faced Boston, was the earliest area of East Boston to be settled. A bridge to Chelsea was built, roads were laid out, and houses were built. Much of this activity was spurred by the formation of the East Boston Lumber Company. During this period, the Boston Sugar Refinery was also founded, which was the first manufacturing establishment in East Boston. They are credited for the creation of white granulated sugar.
