The history of quantum mechanics began with the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck. Planck's hypothesis stated that any energy is radiated and absorbed in quantities divisible by discrete "energy elements", such that each energy element E is proportional to its frequency ν. Planck insisted that this was simply an aspect of the processes of absorption and emission of radiation and had nothing to do with the physical reality of the radiation itself. However, at that time, this appeared not to explain the photoelectric effect (1839), i.e. that shining light on certain materials can eject electrons from the material. In 1905, basing his work on Planck's quantum hypothesis, Albert Einstein postulated that light itself consists of individual quanta.

how did the theory of biogenesis lead the way for germ theory disease
Many scientists worked on it over the years, however it was James Clerk Maxwell that finally developed the set of partial differential equations that fully and correctly describe their wave behavior.Albert Einstein was the first to correctly describe the photoelectric effect in terms of particles called photons. This lead in the 1930s to the modern quantum mechanical theory of electromagnetic radiation.
The Cathode Ray
1. Discovery of isotopes: not all atoms of the same chemical element are identical. 2. Discovery of the atomic structure: atoms are indivisible by chemical methods but they are divisible with physical methods in components.
His first scientific paper was on the Photoelectric Effect, this was one of the founding theories that ultimately lead to Quantum Mechanics (a theory that Einstein rejected).
it didn't
the atomic bomb was not discovered, it was invented then built.
The theory of causality in metaphysics attempts to answer questions about how or why events happen. It focuses on exploring the relationships and connections between different events and the underlying causes that lead to their occurrence.
experiments with cathode rays lead to the discovery of the Electron.

because of his relentless determination and because his discovery started a chain of events that would lead to the founding of a new nation of freedom for all.

No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
