    On This Day - Jan 20 : de Chancourtois was born

    He was the first person to organise elements by atomic weights, by plotting a graph of the elements around a cylinder with a circumference of 16 units corresponding to the weight of oxygen (O). Elements that appeared above and below each other shared similar periodic properties.
