Christopher Hansteen

Christopher Hansteen was the one who discovered the magnet field around the earth in 1827, which caused strange activity, which we now are familiar with and call The Northern Lights. He was also the very first person to make a magnetic map of the earth, and in his lifetime, he did numerous observations on the Nothern Lights.

Hansteen was supposed to become a naval officer. However, he eventually became a lawyer, and therefore started his law studies in 1802. It is also worth noticing that he later decided to quit his law studies, and became a researcher.
