Pierre Louis-Dreyfus was one of four children born to Charles Louis-Dreyfus (1870–1929), a merchant and ship-owner, and Sarah Germaine Hément. His family was Jewish. His paternal grandfather, Léopold Louis-Dreyfus, founded the Louis Dreyfus Group in 1851. He had two siblings, brother François Louis Dreyfus (1909–1958) and sister, Arlette Louis Dreyfus (1911–2001).
After the war, he returned to the family business, Louis-Dreyfus and Co where he became first Vice-President and then served as CEO from 1967 until 1975. He significantly expanded the maritime trade of the company under his direction. The company, now known as Louis Dreyfus Group, had $46 billion in sales in 2011. Upon retirement, his son, Gérard Louis-Dreyfus, headed the company.
