If you check the textbooks, you will find FORTRAN listed as the first high level programming language. Thought up by John W. Backus who disliked writing programs and decided to create a programming system to help make the process much easier, the use of FORTRAN greatly reduced the number of programming statements required to get a machine running. By 1963, more than 40 FORTRAN compilers were already available.

Also known as Perottina, Programma 101 was the world’s first commercial PC. It could perform addition, subtraction, multiplication, division, square root, absolute value, and fraction. For all that it could do, it was priced at $3,200 (it was a very different time) and managed to sell 44,000 units. Perottina was invented by Pier Giorgio Perotto and produced by Olivetti, an Italian manufacturer.

It doesn’t look like much but this was the first touchscreen the world has ever known. It’s a capacitative touchscreen panel, with no pressure sensitivity (there’s either contact, or no contact) and it only registers a single point of contact (as opposed to multitouch). The concept was adopted for use by air traffic controllers in the UK up until the 1990s.

Based on C. A. R. Hoare’s concept of class constructs, Ole-Johan Dahl & Kristen Nygaard updated their “SIMULA I” programming language with objects, classes and subclasses. This resulted in the creation of SIMULA 67 which became the first object-oriented programming language.
