Block Drug Company was a pharmaceutical company based in Jersey City, New Jersey, United States, that specialized in dental care products. Its most popular products included Polident denture cleanser, Poli-Grip denture adhesive, Dentu-Creme denture toothpaste, Nytol sleeping pill, Tegrin medicated shampoo for psoriasis, Lava hand soaps (acquired from Procter & Gamble), Beano and Phazyme anti-gas products, Balmex diaper rash ointments, and Sensodyne desensitizing toothpaste.[1]

GlaxoSmithKline (now GSK plc) purchased the company for $1.24 billion in 2001.[2][3]

History

The company was founded in 1907 by Alexander Block, a Russian immigrant who had a small drugstore on Fulton Street in Brooklyn, New York. He turned the company into a wholesaler in 1915, then became a drug manufacturer in 1925, acquiring a 50 percent interest in Wernet's Dental Manufacturing Company.[1]

Block Drug moved its headquarters to Jersey City, New Jersey in 1938.[4]

Although Alexander Block built the company largely through acquisitions, he developed the Polident brand internally during the 1930s.[5] In 1948, Block Drug rolled out the Ammi-i-Dent tooth powder, and in the early 1950s, the company developed Nytol.[6] After Alexander Block's death in 1953,[5] his son Leonard N. Block (1911–2005)[4] took over, eventually becoming the company's chairman.[5] The last major new product the company introduced was Tegrin, in 1964.[5]

Timeline

  • 1971 – The company went public, trading on NASDAQ under the ticker symbol BLOCA and raising $5.2 million in its initial offering.[6] Two years later, another stock sale generated $23 million.[6] Later in the 1970s, Efferdent took over from Polident as the No. 1 brand in its space.[5]
  • 1972 – Block named as its president James Block, who was the grandson of Alexander Block and the nephew of Leonard N. Block.[5] In 1988, James became chairman as his uncle, Leonard N.

Secrecy

Although Block Drug was a public company from 1971 until 2001, it operated much like a private, family-run firm, with the Block family holding all voting shares plus 54 percent of the non-voting stock. In addition, the company never held annual meetings or issued proxy statements.[6]

Aftermath

Leonard N. Block died in 2005 at age 93 after suffering for years from Alzheimer's disease.[4] Block's nephew John P. Roberts was the producer of the Woodstock Festival using money from his Block inheritance.
