Seymour Geisser was a famous mathematician who made important discoveries about statistics. He found ways to test if something was true or not by looking at data. He came up with ways to prove if the data collected from something was accurate. He was especially famous for coming up with a technique of testing that became known as the "Geisser method." This technique is still used today in scientific and statistical research. In summary, Seymour Geisser was a mathematician who used data to make important discoveries about how we can know if something is true or not.
