Abraham Pihl (3 October 1756 – 20 May 1821) was a Norwegian clergyman, astronomer, and architect.

He completed seminary at the University of Copenhagen in 1783, where he had also studied mathematics, mechanics and astronomy.

The building later served as a model for octagonal churches on the western side of Mjøsa.

[4] Pihl developed a large collection of self-made astronomical instruments, and also made telescopes and sextants for others.

[5][6] His interest in practical matters categorized him as a so-called "potato priest" (Norwegian: potetprest).
