Xu Xiake was a Chinese geographer and explorer born in Jiangsu province. Over three decades during the early 17th century, he journeyed to nearly every region of China, including Sichuan, Yunnan, and Tibet. His meticulous travel diaries combined firsthand observations with geographic, geological, and cultural notes. Xu's writings provided one of the earliest detailed accounts of Chinese landscapes, rivers, and mountains. He mapped previously uncharted territories and corrected many errors in contemporary maps. His work later influenced Chinese cartography and historical geography. Despite occasional hardships, including illness and political obstacles, Xu Xiake remained dedicated to his pursuit of geographical knowledge.

Claude Martin was a French-born soldier who rose to prominence in the service of both the French and British East India Companies. Stationed in Bengal in the late 18th century, he earned the rank of major general and became known for his architectural projects, including the grand house at Lucknow known as Constantia. Martin traveled widely throughout India, collecting art and curiosities that reflected his eclectic interests. Upon his death, he bequeathed much of his fortune to establish the La Martiniere schools in Lucknow, Kolkata, and Lyon. His philanthropy has had a lasting impact on education in India and France. Martin's life combined military service, exploration, and a passion for learning and culture. He died in 1800, leaving a legacy of cross-cultural engagement and institutional benefit.

Zebulon Montgomery Pike Jr. (1779–1813) was a United States Army brigadier general and explorer renowned for his expeditions into the western territories acquired in the Louisiana Purchase. In 1806–1807, he led the Pike Expedition, mapping parts of the upper Mississippi River and exploring present-day Colorado, New Mexico, and Texas. His exploration of the Rocky Mountains culminated in the naming of Pike's Peak in his honor. Pike's leadership and cartographic work significantly expanded American geographic knowledge of the Southwest. He was mortally wounded in 1813 during the War of 1812 at the Battle of York. Despite his early death at age 33, Pike's legacy endures in the mountains that bear his name.

William John Wills (1834–1861) was an English surveyor and medical practitioner who played a central role in the Burke and Wills expedition across Australia in 1860–61. After training in medicine, he joined the Victorian Exploring Expedition and was appointed second-in-command. He and Robert Burke reached the Gulf of Carpentaria, becoming the first Europeans to do so, but died on the return journey due to exhaustion and lack of supplies. Wills's meticulous journals provided lasting insight into the challenges of exploring Australia's interior. His story remains a poignant testament to the era of heroic exploration.

Born in 1903 in Queensland, Harold Gatty was largely self-taught in the art of navigation. He rose to fame by serving as the navigator on Wiley Post's record-setting around-the-world flights in the early 1930s. Gatty later published pioneering texts on air navigation, which became essential guides for pilots. During World War II, he advised airlines and military units on long-distance route planning. His innovations helped transform aviation into a global enterprise. Gatty died in 1957, celebrated for his contributions to safe and precise air travel.
