If one is to say who Albert Einstein's great role model in the history of physics may have been, one is quite right in naming the Scotsman James Maxwell, who in the 19th century managed to understand electricity and magnetism as a unit, which today is called electromagnetism. Maxwell was able to describe light as the movement of an electromagnetic wave, which was a problem when Einstein began studying physics. The explanation of motion actually belonged to the field of mechanics, which Isaac Newton had founded, but his theory did not fit in with Maxwell's theory.
The light that the Scotsman had produced electromagnetically moved at a constant speed, which was not envisaged by Newton. Einstein's desire to unify the two theories led him to establish the special theory of relativity and to unify the basic quantities of space and time into one space-time. Incidentally, Alexander von Humboldt had already developed an idea of this. While observing the sea of stars at night, he had noticed that his view of the cosmos was not only in space, but also in time, as the stars are not seen as they are now, but as they were when the light emanated from them. Actually, one would expect Einstein to be happy about every unit that can be found in two parts, but in the end the opposite was the case. In 1935, he attempted to expose quantum mechanics, which he had initiated but disliked, as incomplete because it described two microscopic objects that had once interacted as a unit even when they were far apart. Two atomic existences remained connected by something - they formed a whole that had no parts in terms of measurement - which was described with the pretty word "entanglement" and for the proof of which the Nobel Prize of 2022 was awarded. Einstein railed against this interaction throughout his life, deriding it as a "spooky action at a distance". When Newton explained the falling of an apple onto the earth as an attraction of masses, this also had to be understood as a spooky action at a distance in the 17th century, but only until Maxwell was able to connect the two objects - the apple and the earth - through a proximity effect with the idea of fields. This has yet to happen with entanglement.
