Søren Peter Lauritz Sørensen (9 January 1868 – 12 February 1939) was a Danish chemist, known for the introduction of the concept of pH, a scale for measuring acidity and alkalinity. Sørensen was born in Havrebjerg Denmark in 1868 as the son of a farmer. He began his studies at the University of Copenhagen at the age of 18.

Sørensen (1868–1939), who held a PhD from the University of Copenhagen, directed the chemical department of the Carlsberg Laboratory, which was supported by the beer company of the same name, brewing being one of the oldest chemical industries. At the time, he was working on the effect of ion concentration in the analysis of proteins.

His doctoral dissertation (1899) concerned the chemistry of cobaltic oxides.

Danish biochemist best known for introducing the pH (potential of hydrogen) scale for measuring the acidity or alkalinity of solutions (1909). Sørensen did extensive work on enzymes and proteins. His laboratory successfully crystallized egg albumen in 1917, an important step in attempts to characterize proteins.

On this day (9th January) in 1868, Danish chemist Søren Sørensen was born. He’s best known for developing the pH scale, which we’ve likely all encountered, to measure the acidity or alkalinity of solutions. This graphic gives a brief overview of the pH scale and what it means.
