Warner-Lambert Co. - Specimen Stock Certificate

Specimen Stock printed by Security-Columbian United States Banknote Company. Warner–Lambert was an American pharmaceutical firm that originated from the merger of two distinct entities. The first of these was established in 1856 by William R. Warner, who opened a drug store in Philadelphia. Warner is notable for developing a tablet coating process, which earned him recognition in the Smithsonian Institution. The second entity was founded by Jordan Wheat Lambert, who created the Lambert Pharmacal Company in St. Louis, renowned for its production of Listerine. The two companies united in 1955, resulting in the formation of Warner–Lambert. Over the years, the company grew significantly through various mergers and acquisitions, positioning itself as a global competitor across multiple sectors. In 1956, Warner–Lambert acquired Nepera Chemical, known for Anahist, from the Lasdon family, many of whom subsequently took on roles as officers and directors within the newly merged organization. In 1962, the company purchased American Chicle, one of the largest producers of gums and mints worldwide.

The acquisition of a small cough tablet manufacturer in the United Kingdom in 1965 led to the international success of the Halls Mentho-Lyptus brand. In 1976, Warner–Lambert acquired Parke-Davis, a company founded in Detroit in 1866 by Hervey Parke and George Davis. This was followed by the acquisition of Wilkinson Sword in March 1993 and Agouron Pharmaceuticals in January 1999. Its subsidiary, Parke-Davis, marketed the antidiabetic medication Rezulin, which received FDA approval in January 1997 but was withdrawn in early 2000. By the late 1990s, Warner–Lambert had formed a partnership with Pfizer to launch its drug Lipitor, which debuted in January 1997 and achieved $1 billion in domestic sales within its first year. In February 2000, Pfizer acquired Warner–Lambert along with all its subsidiaries. The headquarters of Warner–Lambert in Morris Plains, New Jersey, was subsequently utilized by Pfizer, Johnson & Johnson, and Honeywell.
