("Briefing: Pharmaceuticals; Drug Company" ) ''The New York Times'' (October 15, 2000)〕 == 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 and then became a drug manufacturer in 1925, acquiring a 50 percent interest in Wernet's Dental Manufacturing Company.〔 Block Drug moved its headquarters to Jersey City, New Jersey in 1938. Although Alexander Block built the company largely through acquisitions, he developed the Polident brand internally during the 1930s. In 1948, Block Drug rolled out the Ammi-i-Dent tooth powder, and in the early 1950s, the company developed Nytol. After Alexander Block's death in 1953,〔 his son Leonard N. Block (1911–2005)〔 took over, eventually becoming the company's chairman.〔 The last major new product the company introduced was Tegrin, in 1964.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Block Drug」の詳細全文を読む スポンサード リンク
