John Stokes is an Irish mathematician best known for his contributions to mathematics and physics in the 19th century. He was born on September 17, 1812, and is particularly recognized for his work in fluid dynamics and mathematical physics. One of his most notable contributions is the Stokes theorem, which relates surface integrals of vector fields over a surface to line integrals around the boundary of that surface.

Johannes Droste is a German artist and designer known for his work in various mediums, including graphic design and illustration. He may not be widely known in mainstream culture but could have made a significant impact in specific art or design communities.

Johann Rahn (1622–1676) was a Swiss mathematician and one of the early figures in the field of mathematics during the 17th century. He is best known for his work in algebra and for authoring the book "Teutsche Algebra," published in 1659, which was one of the first texts to present algebra in the German language. This work helped to popularize algebra in the German-speaking regions of Europe.

Joan Daemen is a Belgian cryptographer known for his significant contributions to the field of cryptography and cryptographic algorithms. He is perhaps best known as one of the co-designers of the AES (Advanced Encryption Standard) candidate known as Rijndael, which ultimately became the standard for symmetric key encryption adopted by the U.S. National Institute of Standards and Technology (NIST) in 2001.
