Count Ferdinand von Zeppelin (born Constance, Baden, 1838; died Berlin, Germany, March 8, 1917) was a German scientist. He traveled to the United States during the Civil War. He went up in Union hot air balloons and realized the importance of air travel. He returned to Europe and developed lighter-than-air dirigibles. These dirigibles are sometimes called Zeppelins. Idea: Children could check out how we use dirigibles today and find out why we do not use them extensively.
