Andrew Carnegie may be best known for his steel company and Carnegie Hall, but he was also a major philanthropist of his era. Between 1889 and 1919, Carnegie funded the building of more than 1,000 libraries built across the United States. One such library was erected in Lompoc in 1911. The structure, a registered historic landmark, now houses the Lompoc Museum. To celebrate the building’s 100th birthday, the museum is throwing a bash. The theme is “Party Like It’s 1911” and so will feature events popular at that time, such as a bean bag toss, hopscotch, croquet, lawn bowling, kids’ craft tables, a cake walk, and photo booth. There will also be live music. The party takes place Sunday, August 14, 1-5 p.m., at the Lompoc Museum (200 S. H St., Lompoc). For more info, call 736-3888 or visit lompocmuseum.org.
