 ## ChucK History
 ChucK was created in the early 2000s at Princeton University by [Ge Wang](https://ccrma.stanford.edu/~ge/) and [Perry R. Cook](https://www.cs.princeton.edu/~prc/), while Ge was a Ph.D. student advised by Perry in the Computer Science Department. The first version of ChucK was released under a GPL license in 2003. Many researchers, teachers, and artists have contributed to ChucK's evolution over the years. [Spencer Salazar](https://ccrma.stanford.edu/~spencer/) created [miniAudicle](https://github.com/ccrma/miniAudicle), a GUI-based integrated development environment for ChucK in 2004 (this IDE, in addition to the command line version of ChucK, remains largely how ChucK is distributed and used today). The [Princeton Laptop Orchestra](https://plork.princeton.edu/) (PLOrk), founded by [Dan Trueman](https://manyarrowsmusic.com/) and Perry Cook in 2005, began using ChucK for teaching as well as instrument and sound design. In 2006, [Rebecca Fiebrink](https://researchers.arts.ac.uk/1594-rebecca-fiebrink) and Ge Wang created ChucK's audio analysis framework, expressed through unit analyzers--the analysis counterpart to unit generators. Ge join the faculty at Stanford University's CCRMA in 2007, and ChucK research and development became distributed, with developers at Princeton, Stanford, and elsewhere. The [Stanford Laptop Orchestra](https://slork.stanford.edu/) (SLOrk) was founded in 2008 at CCRMA, where ChucK continued to be a tool for instrument design and teaching. In that same year, the mobile music startup Smule was co-founded, which used ChucK on the iPhone (codenamed "ChiP") as a real-time audio engine for its early apps: [Ocarina](https://artful.design/ocarina/), Sonic Lighter, Zephyr, and Leaf Trombone: World Stage. Meanwhile, ChucK continued to find its way into computer music curricula, including at Stanford, Princeton, CalArts. In 2015, the book [_Programming for Musicians and Digital Artists: Creating music with ChucK_](https://www.amazon.com/Programming-Musicians-Digital-Artists-Creating/dp/1617291706/) was published, authored by Ajay Kapur, Perry Cook, Spencer Salazar, and Ge Wang. Around the same time, Kadenze introduced the online course [Introduction to Real-Time Audio Programming in ChucK](https://www.kadenze.com/courses/introduction-to-programming-for-musicians-and-digital-artists/info). Romain Michon and Ge Wang integrated FAUST and ChucK to create [FaucK](https://ccrma.stanford.edu/~rmichon/fauck/). In 2017, Jack Atherton created [Chunity](https://chuck.stanford.edu/chunity/), which enables one to program ChucK inside the Unity game development framework. In 2018, Ge write about ChucK in [_Artful Design: Technology in Search of the Sublime_](https://artful.design/), a photocomic book about the importance of cultural awareness in the shaping of technology. ChucK now runs natively in web browsers ([WebChucK](https://chuck.stanford.edu/webchuck/)) and can be programmed directly in the [WebChucK IDE](https://chuck.stanford.edu/ide/).
