Nikolaus Gradwohl was born in 1976 in Vienna, Austria, and always wanted to become an inventor like Gyro Gearloose. When he got his first Atari, he figured out that being a computer programmer was the closest he could get to that dream. He wrote programs for nearly anything that can be programmed, ranging from an 8-bit microcontroller to mainframes for a living. In his free time, he likes to gain knowledge of programming languages and operating systems.
He is the author of Processing 2: Creative Coding Hotshot, Packt Publishing.
