Who is S.P.L. Sorensen? | assets



Google (googl) today celebrates a little known but influential scientist with Google Doodle.

The Danish scientist S.P.L. (Soren Peder Lauritz) Sorensen is the man who invented the pH scale (remember those pink and blue stripes from your high school chemistry class?) He developed the method for measuring acidity and alkalinity in the year 1909 during the study of the effect of ion concentration on proteins. Today, the method is of enormous importance for daily needs such as clean water and medicine.

Sorensen was born in 1868 in Havrebjerg, Denmark. He studied at the University of Copenhagen with the aim of studying medicine, but made a career as a scientist. He was head of the prestigious Carlsberg Laboratory in Copenhagen for 37 years, where he worked alongside his second wife, Margrethe Høyrup Sørensen. He worked in the laboratory until his death at the age of 71
