who originated the Kjeldahl method for the laboratory determination of the nitrogen content in organic compounds. This was of great value for applications in agriculture, medicine and drug manufacture. It replaced the former procedure that were inexact and time-consuming, and remains in use to the present time. From 1876 until his death, he was the director of the Carlsberg laboratory (a research institution of the Carslberg brewery). He developed his method of measuring nitrogen content to investigate the amount of protein in grain, which was relevant to protein transformation during beer fermentation. The method was reported to the Chemical Society of Copenhagen on 7 Mar 1883.
