Danny Cohen (December 9, 1937 – August 12, 2019) was an Israeli-American computer scientist specializing in computer networking. He was involved in the ARPAnet project and helped develop various fundamental applications for the Internet. He was one of the key figures behind the separation of TCP and IP (early versions of TCP did not have a separate IP layer); this allowed the later creation of UDP.[1][2]
Cohen is probably now best known for his 1980 paper "On Holy Wars and a Plea for Peace"[3] which adopted the terminology of endianness for computing (a term borrowed from Jonathan Swift's Gulliver's Travels). Cohen served on the computer science faculty at several universities and worked in private industry.

...which bit should travel first, the bit from the little end of the word, or the bit from the big end of the word? The followers of the former approach are called the Little-Endians, and the followers of the latter are called the Big-Endians.
