"In 1786, the German scientist Georg Christoph Lichtenberg described the advantages of basing a paper size on an aspect ratio of √2 in a letter to Johann Beckmann. The formats that became ISO paper sizes A2, A3, B3, B4, and B5 were developed in France."
"This ratio has the unique property that when cut or folded in half widthwise, the halves also have the same aspect ratio."
