Johannes Martin Bijvoet ForMemRS[1] (23 January 1892, Amsterdam – 4 March 1980, Winterswijk) was a Dutch chemist and crystallographer at the van 't Hoff Laboratory at Utrecht University.

In 1951, using an X-ray tube with a zirconium target, Bijvoet and his coworkers Peerdeman and van Bommel achieved the first experimental determination of the absolute configuration of sodium rubidium tartrate.

In their later publication in Nature,[5] entitled "Determination of the absolute configuration of optically active compounds by means of X-rays", the authors conclude that: thus confirming the preceding decades of stereochemical assignments.
