Spontaneous generation was the idea that living thoings could develop directly from non-living materials. (See http://www.Biology.clc.uc.edu/courses/bio114/spontgen.htm). Experiments carried out by the French scientist Louis Paeteur provided evidence against this idea. (See http://www.kent.k12.wa.us/staff/TimLynch/sci_class/chap01/pasteur.html).
Through scientific examination: experiments whose results are obtained from comparisons noted through Observation.
The name oxygen was coined in 1777 by Antoine Lavoisier,whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion. Source: http://en.wikipedia.org/wiki/Oxygen
The experiments were being done by Ernest Marsden, and Hans Geiger, under the supervision of Ernest Rutherford.
One example of a scientist whose work was largely ignored during his lifetime is Gregor Mendel. His experiments with pea plants led to the discovery of the basic principles of genetic inheritance, but his work was not widely recognized until after his death.
Gregor Mendel's work was important to science because he discovered the principles of heredity through his experiments with pea plants, which laid the foundation for the field of genetics. His laws of inheritance helped explain how traits are passed down from generation to generation, leading to a better understanding of genetics and evolution. Mendel's findings were revolutionary and have had a lasting impact on the field of biology.
Redi and Pasteur helped to disprove spontaneous generation.
Lazzaro Spallanzani was an Italian abbot and biologist who conducted experiments that built upon and refuted Needham's findings on spontaneous generation. Spallanzani's controlled experiments showed that microorganisms did not spontaneously generate but were carried in the air and required contact with living matter to grow.
Franz Mesmer's experiments with "animal magnetism" in the 18th century are often cited as attempts to prove the existence of a life force known as "vital energy." His work laid the foundation for the development of hypnosis and the concept of energy healing.
There are quite a few pathologists by the name of Reed, but perhaps you are asking about the more famous Walter Reed. Walter Reed was a pathologist in the US Army whose experiments proved that mosquitos carry and transmit yellow fever.

Redi's theory, known as spontaneous generation, proposed that living organisms could arise from nonliving matter. In his famous experiment with the meat and fly larvae, Redi demonstrated that maggots do not spontaneously generate on rotting meat but instead come from eggs laid by flies. This experiment helped to disprove the idea of spontaneous generation.
