Richard Yates (novelist): Richard Yates (February 3, 1926 – November 7, 1992) was an American fiction writer, identified with the mid-century "Age of Anxiety".  His first novel, "Revolutionary Road", was a finalist for the 1962 National Book Award.  His first short story collection, "Eleven Kinds of Loneliness", brought comparisons to James Joyce.  His critical acclaim, however, was not reflected in commercial success during his lifetime, though interest in Yates has revived somewhat since his death, partly because of an influential 1999 essay by Stewart O'Nan in the Boston Review, a 2003 biography by Blake Bailey and the 2008 Academy Award-nominated and Golden Globe-winning film "Revolutionary Road", starring Kate Winslet and Leonardo DiCaprio.

Eleven Kinds of Loneliness: Eleven Kinds of Loneliness is a collection of short stories written by Richard Yates from 1951 to 1961.  All of the stories in "Eleven Kinds of Loneliness" also appeared in the posthumously released "Collected Stories of Richard Yates" (2001).

Gov. Richard Yates House: The Gov. Richard Yates House is a historic house located at 1190 Williams Boulevard in Springfield, Illinois.  The house was built in 1904-05 for Illinois governor Richard Yates, Jr. Architects Helmle and Helmle designed the house, which has Romanesque Revival and Queen Anne influences.  The house's first floor has rusticated stone walls, as do both stories of the turret on the west side; it is a rare example of rusticated stone in a residential Helmle & Helmle design.  The front entrance opens to a great hall, which connects the interior rooms; this arrangement allowed Yates to host political gatherings in his home.  A landing in front of the fireplace provided a raised space for Yates or his guests to give speeches.  Yates left the governor's office the same year his house was completed; he later served in the U.S. House of Representatives from 1919 to 1933.
