Markus Persson

Markus Alexej Persson, more commonly known as Notch, is the creator of Minecraft and one of the founders of Mojang AB.

Biography
Persson started programming at the age of seven, using his dad's Commodore 128. He produced his first game (a text-adventure) at the age of eight, with the help of type-in programs. In 2005 he started working as a game developer for King.com, which he left in 2009 to work as a programmer at Jalbum. After Minecraft sales grew he moved from full-time to part-time at Jalbum and then eventually left to focus full-time on Minecraft in June 2010, many of the Mojang employees (including CEO Carl Manneh) are also ex-Jalbum employees. Outside of work he frequently takes part in competitions, including Ludum Dare, LD12 and the Java 4K Game Programming Contest. He lived in Denmark before he moved to Sweden with his parents and went to school there.

Persson had his own part of the Mojang website that could be found at mojang.com/notch. This subdirectory has since been removed.

Persson sold Mojang and all of its assets to Microsoft on September 15, 2014. In a lengthy blog post, Notch states "I love games and I love to program, but I don’t make games with the intention of them becoming huge hits, and I don’t try to change the world." He then goes on to say that "I’ve become a symbol. I don’t want to be a symbol, responsible for something huge that I don’t understand, that I don’t want to work on."

Persson left Mojang on November 5, 2014 along with the other founders. He writes "As soon as this deal is finalized, I will leave Mojang and go back to doing Ludum Dares and small web experiments. If I ever accidentally make something that seems to gain traction, I’ll probably abandon it immediately."

Three splash messages which referred to Persson - “Made by Notch!,” “The Work of Notch!,” and “110813!” (the date that Persson got married) - were removed from the game in 19w13a. This was likely because of controversy over transphobic tweets Persson wrote earlier that March.
