Korpi was a male Klingon, and head of the House of Korpi. He was a scientist, and was the son of a long line of scientists. He had at least one son, K'pril.
Korpi presumably died in the mid 23rd century. His house was dissolved after his son sided with Admiral Loski during a brief civil war circa 2269. (TNG short story: "I Am Klingon")
