André-Marie Ampère was born in Lyon, France on January 20, 1775.
Ampère’s father actualized the ideal of "education direct from nature" by allowing his son to educate himself within the walls of his well-stocked library.
Ampère immediately set to work developing a mathematical and physical theory to understand the relationship between electricity and magnetism
Most important was the principle that came to be called Ampère's law which states that the mutual action of two lengths of current-carrying wire is proportional to their lengths and to the intensities of their currents.
Ampère also offered a physical understanding of the electromagnetic relationship, theorizing the existence of an “electrodynamic molecule” that served as the constituent element of electricity and magnetism.
Yet, his health began to fail, and he died while performing a university inspection on June 10, 1836 in Marseille.
