In 1914, Fisher began teaching high school mathematics and physics in order to serve his country as he was rejected from the army because of his eyesight.
Fisher was little known then, and the fact that Pearson had gone over his head and criticized the method of maximum likelihood that Fisher had used, and labeled it inverse inference, something Fisher had deliberately tried to avoid.

Although at this stage Fisher was only starting out on his career, he felt angry that Pearson had published an article which was critical of his results without telling him that he was about to do so.

Fisher set out as a convinced Darwinian and Mendelian, and his first tasks were concerned with expressing the well-established results of the biometricians, such as phenotypic correlations among relatives, in terms of Mendel's irreducible particles.
All this is not to say that Fisher was a naive pan-selectionist - believing that all variation is adaptive and that all adaptation is perfection - to the contrary, he saw populations as continually tracking, with a time-lag, some moving environmental target.
Those 'organisms' [Fisher means species] which could not keep up in the race would, according to Fisher, become extinct; the chief risk, he thought, was to have small population size, and therefore to lack a sufficient supply of mutations to feed into the [adaptational] flux.....

 Fisher exact test online. For table analysis, including the median test
The Fisher's Exact test procedure calculates an exact probability value for the relationship between two dichotomous variables, as found in a two by two crosstable.
The one-sided probability for the Fisher exact test is calculated by generating all tables that are more extreme than the table given by the user, in one direction.
In the case of the Fisher this jumping is dependent on the number of different tables that can be produced given the margins.
