The Museum of Science and Industry (MSI) is located in Chicago, Illinois, USA in Jackson Park, in the Hyde Park neighborhood adjacent to Lake Michigan. It is housed in the former Palace of Fine Arts from the 1893 World's Columbian Exposition. Initially endowed by Sears, Roebuck and Company president and philanthropist Julius Rosenwald, it first opened in 1933 during the Century of Progress Exposition. It is also the largest science museum in the western hemisphere. Among its diverse and expansive exhibits, the Museum features a working coal mine, a German submarine (U-505) captured during World War II, a 3,500-square-foot (330 m) model railroad, the first diesel-powered streamlined stainless-steel passenger train (Pioneer Zephyr), and the Apollo 8 spacecraft which flew the first humans to the Moon. Based on 2009 attendance, the Museum of Science and Industry was the third largest cultural attraction in Chicago. David R. Mosena has been President and CEO of the Museum since 1998.
