Jacob Jan Alexander Wijs[2] (12 November 1864 – 13 December 1942) was a Dutch chemist. He spent much of his career at the oil factory in Delft, where he studied the iodine value. In 1898 he described the addition of iodine monochloride to the double bond in alkenes to give chloro-iodo alkanes. This reaction was later named the Wijs-Hanuš method, and the reagent that Wijs used in his demonstration, namely iodine monochloride in glacial acetic acid, the Wijs reagent.[3]
