Johann Gregor Mendel (1822 - 1884) was an Austrian biologist, meteorologist, mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brünn (Brno), Margraviate of Moravia. Mendel gained posthumous recognition as the founder of the modern science of genetics. Though farmers had known for millennia that crossbreeding of animals and plants could favor certain desirable traits, Mendel's pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity, now referred to as the laws of Mendelian inheritance.

Jacques Monod (1910–1976) was a French molecular biologist who, together with François Jacob, uncovered how genes are regulated in bacteria through the lac operon. Their work laid the foundation for modern gene regulation and earned them the Nobel Prize in Physiology or Medicine 1965 (shared with André Lwoff).

Jean Rostand (1894–1977) was a French biologist known for his work in genetics and experimental embryology. He conducted important studies on amphibians and developmental anomalies.

I was surprised to learn that there is a bridge in Israel called "the Double Helix Bridge", known also as "DNA Bridge". On February 10, 2016, Israel issued a stamp features the bridge.


The stamp was issued in se-tenant contains two different bridge stamps.
