The Waterloo Chapter is named for the city in which it is located. The chapter was organized December 8, 1898.

The Waterloo Chapter has placed a DAR marker at two historical sites.

First Log House in Waterloo

In 1846, Charles and America Mullan built the first log house in what is now Waterloo. In 1852, on the same site, they built the first frame house. DAR marked the original site in 1925 with an inscribed bronze plaque secured to an Iowa boulder.

Because of the relocation of Highway 218, the DAR marker that was originally dedicated in 1925 was moved to the site of the first log house. The marker can be viewed at the Park Commission, 1101 Campbell Avenue, in Waterloo.

Lou Henry Hoover's Birthplace

Lou Henry Hoover was the wife of Herbert Hoover, 31st President of the United States.  Lou Henry was born in Waterloo, Iowa, on March 29, 1875.  Her father was Charles D. Henry, a bookkeeper at a Waterloo bank. Because of her mother's health, the Henrys moved to California in 1885. Lou graduated from Stanford University in 1898 and met Hoover as a freshman while they were both working in the University's geological laboratory.  The original site of the Henry home in Waterloo was marked by DAR in 1967 but, due to the relocation of Highway 218, the marker was moved to the Grout Museum of History and Science for display. The original site was located at West 4th and Washington streets.  The Grout Museum is located at the Howery Auditorum, 503 South Street, Waterloo.
