Lloyd's win was capped by a three at the 461-yard (422 m) finishing hole. Anderson needed a four at the last to tie Lloyd; he reached the green in three, but his putt came up 6 feet (1.8 m) short. Anderson waited four more years for first of his record four U.S. Open titles in five years.

The 1900 U.S. Open was the sixth U.S. Open, held October 4–5 at Chicago Golf Club in Wheaton, Illinois, a suburb west of Chicago. On a tour of the United States from Britain, Harry Vardon won his only U.S. Open title, two strokes ahead of his great rival, J.H. Taylor. In the U.S. to promote the Vardon Flyer Ball, Vardon made his first appearance at the U.S. Open. Taylor was also in America on business and decided to enter, creating a highly anticipated matchup between the two great British rivals. Together they formed two-thirds of the Great Triumvirate that dominated British golf at the turn of the century (the third, James Braid, never played in the U.S. Open). On Thursday morning, Taylor opened with 76 for a two-shot lead, but an 82 in the afternoon put him one back of Vardon after 36 holes. On Friday morning, Vardon's 76 opened up a four-stroke lead over Taylor, who was seven clear of the field. Despite an 80 in the afternoon for 313, Vardon prevailed by two, as Taylor shot 78 for 315. Local Chicago pro David Bell was a distant third at 322.Neither Vardon nor Taylor won another major outside The Open Championship, which they won a combined eleven times. Vardon did not play in the U.S. Open again until 1913, when he and Ted Ray lost a playoff to amateur Francis Ouimet. He was also runner-up in his third and final Open appearance, in 1920. Taylor played the U.S. Open only once more, also in 1913, and was thirtieth.

McLeod had a three-stroke lead after 54 holes, but finished with 83 for 308. Simpson posted 79-75 for 307, while Brady tied Simpson with a final round 75.

McDermott took the lead at the 15th after Brady missed a four-footer (1.2 m) for par, then sealed the championship with an approach to the par-5 18th that settled ten feet (3 m) from the hole. He two-putted for birdie and 80, two strokes ahead of Brady and five clear of Simpson at 85.At 19, McDermott became the youngest U.S. Open champion, a mark that still stands, and was also its first American-born champion. He successfully defended his title the following year, but by 1914 he began suffering from mental illness and his career was essentially over at age 23. The Open Championship in England was held June 26−30 at Sandwich.

DuPage County ( doo-PAYJ) is a county in the U.S. state of Illinois, and one of the collar counties of the Chicago metropolitan area. As of the 2020 census, the population was 932,877, making it Illinois' second-most populous county. Its county seat is Wheaton.Known for its vast tallgrass prairies, DuPage County has become mostly developed and suburbanized, although some pockets of farmland remain in the county's western and northern parts. Located in the Rust Belt, the area is one of few in the region whose economy quickly became dependent on the headquarters of several large corporations due to its close proximity to Chicago. As quarries closed in the 1990s, land that was formerly used for mining and plants was converted into mixed-use, master-planned developments to meet the growing tax base. The county has a mixed socioeconomic profile and residents of Hinsdale, Naperville and Oak Brook include some of the wealthiest people in the Midwest. On the whole, the county enjoys above average median household income levels and low overall poverty levels when compared to the national average. In 2023, Niche ranked four DuPage municipalities (Clarendon Hills at #125, Naperville at #130, Hinsdale at #166, and Lisle at #280) amongst the best places to live in America.

Russell R. Kirt Prairie is a restored tallgrass prairie and savanna within the College of DuPage Natural Areas. A Trail Guide published by the college provides background information and ecological notes. In addition to the mesic prairie and oak savanna, the site also includes a small hill prairie, swale, marsh and wetland areas.: 8 Professor Russell R. Kirt states on the back cover of his book Prairie Plants of the Midwest: Identification and Ecology that he "began restoring prairie in 1974, two years after Ray Schulenberg of the Morton Arboretum introduced him to the prairie". In 1981 he started the restoration project by obtaining grant money from the college's Board Of Trustees, and began collecting native seeds and seedlings from sites within a 40-km radius of the college to ensure local genotypes. In 1984, he reestablished a former farmland and parking lot at the college to prairie with the help of numerous volunteers, including students. The restoration used two methods, either seed broadcast or seedling transplant. Whenever possible, species associations as described by Swink and Wilhelm were planted together. He monitored the site for at least 16 years, and published his findings at the North American Prairie Conference. After 16 years, the Floristic Quality Index (Index Value in Professor Kirt's papers) in areas restored by either method reached about 30, with no significant difference between the two.: 103 The college Board Of Trustees designated the site as West Prairie-Marsh Nature Preserve in December 1993, and renamed it Russell R. Kirt Prairie in November 1999.: 8 The prairie is located less than 100 meters from the college's Health and Science Center, making it the only sizable restored prairie in the U.S. that is within walking distance of a college classroom building, and it is often used for field study by biology, botany, and environmental science classes. The college offers a Prairie Ecology class that focuses on the tallgrass prairie ecosystem, with extensive hands-on studies in the prairie.: 17  Other disciplines that make use of the prairie resource include earth science, art, and photography.
