Thomas Edison National Historical Park is home to Thomas Edison's historic home and lab, where he developed many of his great discoveries and inventions. Edison's home is the Glenmont Estate and the grounds are open for tours and public visits for families and children. Ranger-led tours are available at scheduled times throughout the day for the Laboratory Complex, which includes a phonograph demonstration, a tour of the chemistry building and a look at the Black Maria, the world's first film production studio. There is a Junior Ranger Badge program for children offered here. The park has a bookstore. Reservations are only required for groups of more than 10 people.
