Avogadro’s number was actually discovered/named by Jean Perrin and Avogadro never saw or used the number! Avogadro’s law is something else. I think they named it Avogadro’s number to honor him because he never got any recognition for his law until after his death.

Reply to comment by OccludedFug in TIL Amedeo Avogadro's contribution to chemistry, known as Avogadro's law, did not initially receive much attention when he published his paper in 1811. It was only a century later that his work was recognized, when the King of Italy attended a meeting commemorating the paper's 100th anniversary. by dustofoblivion123
