Our old friend Conrad Poppenhusen established a rubber factory in College Point in the 1850s; within a couple of decades, a number of other rubber men had set up shop in town, including Isaak Kleinert, who seems to be mostly remembered for a dress shield he developed. Kleinert's still exists today, now headquartered in Alabama, and bills itself as "the world's authority on sweat protection". I wonder if they've also maintained their position as "makers of America's finest water-proof baby needs".
