    John Townsend Baker


    Baker HistoryThe company now known as Avantor was founded in 1904 by John Townsend (J.T.) Baker.

    J.T. Baker was studying chemistry at Lafayette College in Easton, Pennsylvania, when he realized that the laboratory chemicals he was using in class were not sufficiently pure to facilitate accurate results. He decided to take matters into his own hands. In 1904, he founded the J.T. Baker Chemical Company along the Delaware River near the border of New Jersey and Pennsylvania.

    The mission of the J.T. Baker Chemical Company was to produce chemicals of the "highest degree of purity commercially available."


    A Global Evolution

    History - Global Evolution ImageWhen it was founded in 1904, the J.T. Baker Chemical Company employed 20 individuals in Phillipsburg, New Jersey. Today, Avantor has operations throughout the world and is the global supplier of ultra-high-purity materials for the life sciences and advanced technology markets.

    While the company has grown its manufacturing capabilities, product portfolio and global reach, our goal of providing high-quality materials to our customers around the world has not changed.
