Like all great enterprises, ADP began with an idea. One day, 21-year-old Henry Taub visited a company where a key employee had become ill. The payroll wasn’t done, and workers weren’t being paid on time. Where others saw a problem, Henry saw an opportunity. Automatic Payrolls, Inc, a manual payroll processing service, was born from his insight.
