d. December 17, 1947, Copenhagen, Denmark

Johannes Nicolaus Brønsted was Danish physical chemist known for a widely applicable acid-base concept identical to that of Thomas Martin Lowry of England. Though both men introduced their definitions simultaneously (1923), they did so independently of each other. Brønsted was also an authority on the catalytic properties and strengths of acids and bases. His chief interest was thermodynamic studies, but he also did important work with electrolyte solutions.

Johannes Nicolaus, c. 1890
The son of a civil engineer, Johannes Nicolaus was born on February 22nd, 1879 in Varde, a small town in West Jutland. His mother died soon after his birth, and his father remarried. However, Johannes was only 14 years old when his father also died. These tragic family circumstances must have left Johannes and his elder sister Ellen in a very trauma

Johannes Nicolaus Brønsted

Danish physical chemist (1879–1947)

Johannes Nicolaus Brønsted (Danish:[joˈhænˀəsne̝koˈlɛːusˈpʁɶnsteð]; 22 February 1879 – 17 December 1947) was a Danishphysical chemist who is best known for developing the Brønsted–Lowry acid–base theory; he developed the theory at the same time as (but independently of) Martin Lowry.[1]

Biography

Brønsted was born in Varde, Denmark on 22 February 1879. His mother died shortly after his birth, and his father died when Brønsted was 14 years old; he then moved to Copenhagen with his older sister and his stepmother.[2] In 1897, Brønsted began his studies as a chemical engineer at the Polytechnic Institute in Copenhagen. After his first degree, Brønsted changed fields and received his magister degree in chemistry in 1902 from the University of Copenhagen. In 1905, he became an assistant at the Chemical Institute and obtained his doctoral degree in 1908. In the same year, Brønsted became a professor of physical and inorganic chemistry at the University of Copenhagen.[3]

chemistry.

Brønsted entered the Faculty of Chemical Engineering at the Technical University of Denmark in 1897. Two years later he received his degree, then left the Technical University and entered the Faculty of Natural Sciences at the University of Copenhagen, from which he obtained the M.S. in chemistry in 1902. After a period of nonchemical research he was appointed assistant at the university’s chemical laboratory in 1905, and from then on he was attached to the university, serving as professor of physical chemistry from 1908.

Since the conclusion of Julius Thomsen’s studies on thermochemistry in 1886, physical chemistry had been somewhat neglected in Denmark. although the work of Ostwald, Arrhenius, and Nernst was followed up in most other countries. Brønsted took over Thomsen’s idea of determining chemical affinity by measuring the maximum work of a chemical process, but instead of using calorimetric determinations, he used electromotive force measurements
