David Parham Reynolds was born on June 16, 1915, in Bristol, Tenn. He graduated in 1934 from the Lawrenceville School, where he was captain of the football team. Four years later, he graduated from Princeton University and joined his three older brothers — William, Richard Jr. and J. Louis — at Reynolds Metals. Mr. Reynolds, who lost an eye playing polo during his junior year at Princeton, owned dozens of thoroughbred racehorses, including Tabasco Cat, who won the 1994 Preakness and Belmont Stakes, the final two legs of the Triple Crown. In retirement, Mr. Reynolds lived at his homes in Richmond, Del Ray Beach, Fla., and Wequetonsing, Mich. His wife, the former Margaret Harrison, died in 1992. In addition to his daughter Margaret Mackell of Richmond, survivors include two daughters, Julie Swords of Lexington, Ky., and Dorothy Brotherton, also of Richmond; six grandchildren; and nine great-grandchildren. Beyond beverage cans and kitchen wrap, Mr. Reynolds promoted the use of aluminum in everyday life and frequently tested ideas on his family. The Reynolds house was outfitted with an aluminum solar-paneled roof; an aluminum Christmas tree graced their home during the holidays; and the family freezer was stocked with foil-wrapped ice cream from the Eskimo Pie Company, a subsidiary of the family metals business. Mr. Reynolds even gave his wife aluminum jewelry, something she wore sparingly, preferring more precious metals.
