The Sumner Simpson Papers

Where the collection comes from

The papers came to light in 1977, in a lawsuit brought by former workers at Raybestos-Manhattan's plant in Passaic, New Jersey. Their lawyer, Karl Asch of Springfield, New Jersey, had filed the suit in federal court in New Jersey on May 6, 1975, against the companies that sold the plant its raw asbestos and against Metropolitan Life. By 1979 it had 668 plaintiffs. Asch had read in Raybestos-Manhattan's 1974 annual report that the company had commissioned Metropolitan Life to survey its factories as early as 1930, and he set out to find those surveys. On April 12, 1977, he deposed William S. Simpson, Sumner Simpson's son and the company's chief executive, at its headquarters in Trumbull, Connecticut. Asked where the records of the Metropolitan Life and Saranac studies were kept, the company's lawyers told him that a carton of Sumner Simpson's personal papers was in a nearby room. After his father died in 1953, William Simpson said, the carton had been kept in the company's vault. Asch spent the next several days going through it. Paul Brodeur told the story in The Asbestos Industry on Trial, II: Discovery, in The New Yorker of June 17, 1985.

Raybestos-Manhattan produced the papers in litigation in May 1977, in numbered volumes headed "R-M Documents Produced May 1977." Johns-Manville kept a copy in its archive as a collection it called the Simpson papers, in a file labeled "Fiber Litigation, Raybestos Manhattan, Sumner Simpson Papers." Johns-Manville's attorneys coded the documents into an index, the "Sumner Simpson Documents," which numbers them 00000 to 05907 and gives each one's date, writer, addressee and a short description. Each page quotes that description. Where the index gets a name or a date wrong, the page says so. Our copies come from Johns-Manville's archive, now held by the Manville Personal Injury Settlement Trust's records facility.
