Edith Roosevelt established the modern role of First Lady and oversaw the building of the West Wing of the White House while her husband Teddy ran the country.
Although Edith Kermit Carow had a teen romance with Teddy Roosevelt, he married someone else. The two were not reunited until after he became a widower. When they moved into the White House in 1901, it wasn't quite big enough for a family of six children, so Edith had a new West Wing built. She also established many of the traditions of the First Lady that remain today.
