Alexander von Humboldt was a German geographer, naturalist and explorer who laid the foundation for the field of biogeography and modern geomagnetic and meteorological monitoring. He had an unrelenting passion for nature and often spent time accumulating samples of plants, insects and shells, and even categorized them. As a child he received lessons in a variety of subjects beginning from languages to economics. However, he was always drawn towards nature and also had an inquisitiveness to know more about it. As a young lad he decided to embark on expeditions in order to satiate his craving for knowledge about the different plants species and also know the earth in a better and vast way. Humboldt also leant about minerals in the mining school where he was a student, and his voyages through England enhanced his knowledge. His study in mineralogy incorporated with the knowledge he accumulated during his expeditions helped him get a mining job in Berlin. He was efficient enough in his duties and soared high in the department. However, he always craved to know more about the earth and exploration was the only means to help him in this. So he left the job and with the fortunes he was entitled to from his mother, he embarked on a new journey. He realized many unknown secrets about nature and shared these with the world, in his renowned book ‘Kosmos’
