January 12 is Johan August Arfwedson’s birthday. Arfwedson was a Swedish chemist who discovered the element lithium.
Arfwedson was from a wealthy family and matriculated early from Uppsala University where he earned both a Law degree and a degree in mineralogy. The law degree allowed him to manage his family’s wealth and the mineralogy degree allowed him to keep busy as an unpaid secretary and notary at the Royal Bureau of Mines at Stockholm. There, he struck up a friendship with one of the leading figures in chemistry, Jöns Jacob Berzelius. Berzelius gave Arfwedson access and working space in his private laboratory.
In 1817, he began investigating the mineral petalite. He found it contained aluminum, silicon, and oxygen. After determining how much of each, he discovered he had only accounted for about 96% of the total mass of his samples. After further experimentation, he discovered the missing part formed salts chemically similar to sodium and potassium. Arfwedson’s new metal came from a rock, so he called it lithium after the Greek word lithos meaning stone.
Arfwedson discovered other minerals carried his new stone metal, but could never successfully isolate lithium in a pure sample. Lithium would not be found in its pure form until 1821 whe

Arfwedson became a student at the Uppsala University in 1803. He completed a degree in Law in 1809 and a second degree in mineralogy in 1812. Later in the year, he received an position in the Royal Board of Mines.
In Stockholm, Arfwedson knew the chemist Jöns Jakob Berzelius. He got access to his private laboratory, which is where he discovered lithium in 1817, during analysis of the mineralpetalite.[1]
He was elected a member of the Royal Swedish Academy of Sciences in 1821.
The rare mineral arfvedsonite was named after him.
