He graduated in medicine at the University of Pennsylvania in 1856, and in 1857 entered the United States Army as assistant surgeon; but, upon the start of the Civil War, he and his brother, a lieutenant in the navy, resigned at the same time with their father, Thomas T. Fauntleroy. He became a surgeon in the Confederate army, and was president of the board for the admission of surgeons, and chief officer on the medical staff of Gen. Joseph E. Johnston, and served with him until the battle of Seven Pines. He was then ordered to build and organize the hospitals at Danville, Virginia, and afterward had charge of the military hospital at Staunton, Virginia, until the war ended. He remained and practised at Staunton after the war, and was for several years superintendent of the lunatic asylum at that place. His contributions to medical literature include papers on potassium bromide, chloral hydrate, the use of chloroform in obstetrical practice, and a "Report upon Advance in Therapeutics," which was printed in the Transactions of the Virginia Medical Society.

Example Input: Question: How old is the producer of Viewtiful Joe? Passage:Viewtiful Joe is a 2.5D side-scrolling action-platformer, released on June 26, 2003. The title character is a parody of tokusatsu superheroes and is trying to save his girlfriend, who has been trapped in "Movieland" by a group of supervillains known as Jadow. To complete his quest, Joe must use his Viewtiful Effects Powers, which are based on camera tricks and special effects used in films. These include "Slow", which simulates bullet time; "Mach Speed", allowing Joe to attack all enemies with his afterimages; and "Zoom In", which triggers a camera close-up and unlocks special attacks. Internally, Capcom treated the game as a "staff-focused project" with the goal of increasing the skills of director Hideki Kamiya. The game achieved a Metacritic score of 93 and won GameCube Game of the Year awards from numerous publications including IGN, GMR, and USA Today. The game sold out its initial shipment of 100,000 to achieve a lifetime total of 275,000 units. Producer Atsushi Inaba considered the game a success, achieving his goals of training staff, keeping a small budget, and selling well. However, these numbers were lower than Capcom expected, prompting the publisher to port Viewtiful Joe to PlayStation 2 in 2004, with expanded features. This version sold 46,000 copies with a slightly lower Metacritic score of 90 owing to the lack of progressive scan and frame rate slowdown generated by the porting process.
