According to bourgas.ru, May 10 is the professional holiday of chemists in Bulgaria.
This decision was made at the general meeting of the Bulgarian Chamber of Chemical Industry back in 2001.

Chemistry is one of the oldest sciences. The first philosophical attempts to explain some phenomena began in ancient Greece. Simultaneously with the doctrine of the four basic elements – fire, water, air and earth, the doctrine of the atom (atomism) arose. Its founders are considered to be Leucippus and Democritus.

In Alexandria, the theories of Plato and Aristotle and practical knowledge about substances, their properties and their transformations were combined. It is believed that the name “chemistry” itself comes from the ancient name of Egypt – “Kem” or “Ham”. The Egyptian god Thoth or his Greek counterpart Hermes became the patron of chemistry in Alexandria.

Jabir ibn Hayyan (Geber), considered by many in the late 8th century as the father of chemistry, developed a new theory of the origin of metals, according to which metals are formed according to two different principles. Gold is considered the ideal metal, and Jabir believes that it requires a special substance, which he calls the philosopher’s stone (Lapis Philosophorum) or elixir. This elixir was supposed to have many other properties – to cure diseases and even give immortality.

Robert Boyle, sometimes called the father of chemistry by some, is credited with applying the modern scientific method and thus beginning to separate chemistry from alchemy.

But the person officially recognized as the founder of modern chemistry is Antoine Lavoisier, the French scientist who formulated the law of conservation of mass of matter.

However, in Russia in the 18th century, Mikhail Lomonosov formulated the law of conservation of matter in chemical reactions and the law of conservation of energy, developing original ideas about the molecular structure and nature of heat.

After Friedrich Wöhler succeeded (albeit accidentally) in synthesizing an organic compound from inorganic compounds in the 19th century, this opened up enormous new possibilities for development in the field of chemistry, and over the centuries more were added to the list of chemical elements.

Do not forget that the Russian scientist Dmitry Mendeleev created the Periodic Table of Chemical Elements (Mendeleev’s table), the idea of ​​which came to the scientist allegedly in a dream.
