An informative, fascinating resource suitable for students, researchers, and general readers, this biographical dictionary is a "who was who" of world and space explorers, giving readers a sense of the human drama—the achievements and the challenges—that those who go where few or none have gone before must face. The explorers covered include Jacques Cousteau, Sir Vivian Fuchs, John Glenn Jr., Aleksei Leonov, Annie Peck, Valentina Tereshkova, and many more.

This biographical dictionary documents the Union army colonels who commanded regiments from Indiana, Kentucky and Tennessee. Entries are arranged first by state and then by regiment, and provide a biographical sketch of each colonel focusing on his Civil War service. Many of the colonels covered herein never rose above that rank, failing to win promotion to brigadier general or brevet brigadier general, and have therefore received very little scholarly attention prior to this work.
