What was Spallanzani known for?

Lazzaro Spallanzani, (born Jan. 12, 1729, Modena, Duchy of Modena—died 1799, Pavia, Cisalpine Republic), Italian physiologist who made important contributions to the experimental study of bodily functions and animal reproduction.

What was Spallanzani’s first step in his experiment?

A few years later (1765 – 1767), Lazzaro Spallanzani, an Italian abbot and biologist, tried several variations on Needham's soup experiments. First, he boiled soup for one hour, then sealed the glass flasks that contained it by melting the mouths of the flasks shut. Soup in those flasks stayed sterile.
