1920
If you are referring to the Aufbau Principle, than I believe it was the Danish physicist Niels Bohr who discovered it around 1920. However, instead of being named after a person, it came from the German phrase Aufbauprinzip which literally translates to "building-up principle."
Aufbau
The tendency of electrons is to occupy orbitals of lowest energy first, in accordance with the aufbau principle. This principle states that electrons fill orbitals from lowest to highest energy levels in order to achieve the most stable electron configuration.
Aufbau principle
Yes, the aufbau principle states that electrons fill orbitals starting with the lowest energy level and filling up to two electrons in each orbital before pairing electrons. This follows the Pauli exclusion principle, which states that each orbital can hold a maximum of two electrons with opposite spin.

The Aufbau principle states that electrons fill orbitals in order of increasing energy levels. Orbital diagrams visually represent the arrangement of electrons in an atom's orbitals. By following the Aufbau principle and using orbital diagrams, we can understand how electrons are distributed in an atom's electronic configuration.
The Aufbau principle states that electrons must be added to elements and ions in a VERY specific order with the lowest energy level being filled first and the highest last. This is where the Aufbau triangle comes in. It shows the order in which the energy levels must be filled.
it is not valid for hydrogen
4f orbital
The Aufbau Principle is also known as the build-up principle because it describes the process of filling electrons into atomic orbitals starting with the lowest energy orbitals and moving towards higher energy levels. This gradual filling up of electron orbitals reflects the building up of an atom's electronic configuration.
