San Diego County Fair In 1954, the fair's name was changed to the Southern California Exposition and San Diego County Fair. In 1970, this was shortened to the Southern California Exposition. The fair was again renamed in 1984 to the Del Mar Fair, which lasted until 2002 when the name San Diego County Fair was reinstated. It is sometimes still referred to as the "Del Mar Fair" by locals.
Merck & Co. In 1953, Merck & Co. merged with Philadelphia-based Sharp & Dohme, Inc., founded by Alpheus Phineas Sharp and Carl Friedrich Louis Dohme in 1845, becoming the largest US drugmaker.[6][7] The merger combined Merck & Co.'s strength in scientific research and chemical manufacturing with Sharp & Dohme's sales and distribution system and its marketing expertise. The combined company kept the trade name Merck in the United States and Canada, and as Merck Sharp & Dohme (MSD) outside North America. In 1965 Merck & Co. acquired Charles E. Frosst Ltd. of Montreal, Canada (founded 1899) and created Merck-Frosst Canada, Inc., as its Canadian subsidiary and pharmaceutical research facility. Merck & Co. closed this facility in July 2010,[8] and the company was renamed Merck Canada in 2011.
