Lyon Gardiner Tyler died of pneumonia on February 12, 1935, at the age of eighty-one. After resigning as president of the College of William and Mary in 1919, he had retired to Lion's Den, his farm in Charles City County, Virginia. Retirement did not end his public activity: he continued to speak, write, and investigate historical records into his later years. His first wife, Anne Tucker, had died in 1921, and in 1923 he married Sue Ruffin; their young sons were part of his later household. The consulted historical biography identifies pneumonia as the fatal illness but gives no dependable sequence of symptoms, treatment, or the length of his final confinement. His continued intellectual activity should therefore not be confused with proof of uninterrupted physical health. He was buried in Hollywood Cemetery in Richmond. The record establishes a final respiratory illness after an extended retirement, while leaving the private course of his last days largely undescribed. He must also be distinguished from his son, Lyon Gardiner Tyler Jr., whose much later life and death belong to another generation.
