This is great stuff. Udo of Aachen being the first discoverer of the Mandelbrot set brings to mind other famous clergymen: Alfred Young, discoverer of Young's Tableux and Young diagrams, which are widely used in mathematical physics and representation theory, was a parish priest in Birdbrook, Essex https://mathshistory.st-andrews.ac.uk/Biographies/Young_Alfred/ https://mathshistory.st-andrews.ac.uk/Biographies/Young_Alfr... Johann Werner (1468-1822), an ordained priest in Nuremberg, discovered a way to determine your position from sightings of the moon, discovered trigonometric identities and worked on conic sections, and was a pioneer of modern meteorology. https://mathshistory.st-andrews.ac.uk/Biographies/Werner/ https://mathshistory.st-andrews.ac.uk/Biographies/Werner/ Marin Mersenne (1588-1648), of Mersenne Prime fame, was a French monk, a member of the The Order of the Minims "having been set up by St Francis of Paula in 1436, was thriving at this time. They believed they were the least (minimi) of all the religions on earth, and devoted themselves to prayer, study, and scholarship. They wore a habit made of coarse black wool with broad sleeves and girded by a thin black cord (as seen in the portraits of Mersenne).

Edwin Abbot (1938-1926) was an ordained priest, schoolmaster, and author who wrote many books including the pop-math books such as "Flatland" as well as "Shakespearean Grammar", "How to write clearly", and exegetical texts on the works of Paul and John in the New Testament, and Koine Greek grammars. John Polkinghome (1930-2021) as an anglican priest, mathematical physicist, and theologian who worked on high energy physics. A student of Murray Gell-Mann at Caltech, he authored many research papers on Scattering matrices, renormalization, pertubation theory, spinors, and other topics in quantum mechanics, with fellowships at SLAC, Cern, Berkeley and Princeton. He was elected to the Royal Society and received a knighthood. https://mathshistory.st-andrews.ac.uk/Biographies/Polkinghorne/ https://mathshistory.st-andrews.ac.uk/Biographies/Polkinghor... Francesco Maria Grimaldi (1618-1663) was a Jesuit priest who worked in mathematics, astronomy, mechanics, and optics. His most famous discovery was the diffraction of light, by creating a prototype of Young's double slit experiment. https://mathshistory.st-andrews.ac.uk/Biographies/Grimaldi/ https://mathshistory.st-andrews.ac.uk/Biographies/Grimaldi/
