Robert Shields (diarist)

Shields was married to Grace Augusta Hotson, with whom he had three daughters: Klara, Cornelia, and Heidi. He died from a heart attack at his home in Dayton, Washington, on October 15, 2007, just over 10 years after the stroke that ended his work on his diary. He was 89 years old.

Shields's self-described "uninhibited", "spontaneous" work was astonishing in its mundaneness, and now fills 91 cartons in the collections of Washington State University, to whom he donated the work in 1999. In a May 2000 interview he said "I've written 1200 poems and at least five of 'em are good." He also claimed to have written the story base for Elvis Presley's film Love Me Tender based on the Reno Gang of Seymour, Indiana, where Shields was born. Copies of the manuscript are at the Kansas State Historical Society's E. P. Lamborn collection. Shields based his manuscript on John Reno's 1879 autobiography, although there is some uncertainty over the authorship of the Reno autobiography, with Shields himself having acted as editor for the only known published copy.

Believing that discontinuing his diary would be like "turning off my life", he spent four hours a day in the office, on his back porch, in his underwear, recording his body temperature, blood pressure, medications, describing his urination and bowel movements, and slept for only two hours at a time so he could describe his dreams. The New York Times summarized the journal as being about anything "from changing light bulbs to pondering God to visiting the bathroom". He also left behind samples of his nose hair for future study. After his stroke in 1997, Shields tried to continue the diary by having his wife write what he told her to write, but she lacked the compulsion and energy to do so and stopped shortly afterward.

Robert William Shields (May 17, 1918 – October 15, 2007) was an American minister and high school English teacher best known for writing a diary of 37.5 million words, which chronicled every five minutes of his life from 1972 until a stroke disabled him in 1997. Shields's diary, which filled 91 boxes, was longer than those kept by the journalist Edward Robb Ellis (21 million words) and the poet Arthur Crew Inman (17 million words), and 30 times longer than that of Samuel Pepys (1.25 million words).
