In 1668, Italian physician Francesco Redi first performed tests with rotting meat that showed that maggots did not form spontaneously as was previously thought. It suggested that living things could only be formed from living things of the same type.

Louis Pasteur in 1861 improved upon the experiments of John Needham, who in 1745 had suggested that living things could form despite sterilization of the medium. Pasteur boiled solutions in beakers that had necks shaped like an S, so that airborne microorganisms could not reach the solution past the neck. Mold did not appear in the unexposed liquid that was boiled, but did in the solution that was exposed to bacteria from the air.

What did Pasteur and Redi's experiments involve and what did they prove or disprove?

Francesco Redi and Louis Pasteur, as well as Lazzaro Spallanzani and John Tyndall, all did scientific experiments (as opposed to philosophical writings) challenging the idea that life could quickly arise in the absence of any life from which other life could grow. This idea, formally dating back to the ancient Greeks, is called "spontaneous generation." The experiments of these four showed that spontaneous generation did not occur in situations that others thought it did. Like any good science controversy, other scientists did experiments that supported spontaneous generation, but Pasteur and Tyndall were able to do experiments that were rigorous enough to unambiguously disprove this idea.

Do you mean abiogenesis? Biogenesis is just cell theory and cells come from cells. Pasteur did not disprove biogenesis or abiogenesis. He disproved spontaneous generation which is a very different thing.
