Some readers have such fond memories of the "Little House" novels about Laura Ingalls Wilder's frontier childhood that they cry when they walk into her Missouri home and see the desk where she wrote many of the books.
This year marks the 75th anniversary of the first publication in 1932 of "Little House in the Big Woods." The story of Wilder's early life in a cabin in 1860s Wisconsin launched a nine-book series that made her a household name, helped by the hit award-winning TV series "Little House on the Prairie" that ran on NBC from 1974 to 1983.
Embraced from the start by America's teachers, the books have been read by or to generations of elementary-school kids, which has helped to keep the books in continuous print. The series has sold more than 41 million copies in the United States and been translated into 40-plus languages, from German and French to Arabic and Japanese.
The white clapboard farmhouse where Wilder and her husband, Almonzo, spent most of their adult lives stands on a hillside among rolling pastures and woods in the Ozarks of southern Missouri. The couple moved here to raise apples and horses after losing their first farm in South Dakota and briefly living in Florida.
Today, the Laura Ingalls Wilder Historic Home and Museum attracts 40,000 visitors a year.
"They're just in awe," tour guide Rebecca Dierksen said of visitors to the museum. "So many of them have wanted to come here for years and then they actually walk in the house."
The 40-acre farm the Wilders bought in 1894 for $400 now includes a museum with artifacts from the author's collection, including a fiddle her father played in Wilder's stories, a quilt made by her sister, Mary, and handwritten manuscripts of the books.
Laura Ingalls Wilder spent more than 30 years painstakingly developing the rocky farm with her husband before sitting down to write about her childhood on the vanished frontier. She was in her early 60s when she attempted her first draft in 1930, a first-person memoir called "Pioneer Girl."
That roughly 200-page manuscript was submitted to publishers and magazines by Wilder's only surviving child, Rose Wilder Lane, a successful writer, journalist and novelist.
