T&H Group has a rich and proud history of serving clients with solutions essential to managing their risk. In 1844, 20 year-old Isaac Tanenbaum was working as a plumber in Manhattan's garment district, where fires often occurred. In response, he developed a sprinkler head that opened when the tallow fuse melted from excess heat. Soon he was installing sprinkler systems, along with a warranty that they would work - if his monthly inspection service was purchased.

In the 1850s, Tanenbaum started selling Fire and Sprinkler Leakage Insurance to his sprinkler clients. By 1860, he had formed a separate insurance office where he developed insurance engineering for safety and loss prevention as a science, combining the company's insurance and sprinkler expertise. Over the next 150 years, the firm grew to become one of the nation's leading full-service insurance brokerage, benefits and surety businesses.
