=============== Acknowledgments =============== A lot of people were involved in the creation of mosaik and mosaik wouldn't be what it is today without any of them: - *Martin Tröschel* and *Astrid Nieße* had the original idea for a tool that lets you integrate existing simulators to perform large-scale Smart Grid simulations. They also accompanied mosaik's development many years as group and project leaders and provided the necessary time and resources for mosaik's development. - *Steffen Schütte* wrote his PhD around mosaik. He and *Stefan Scherfke* are the primary authors of mosaik 1. - *Ontje Lünsdorf* not only contributed code to mosaik 1, but also a lot of ideas. He held countless discussions with Steffen and Stefan whose results often greatly improved mosaik. - *Stefan Scherfke* is the primary author of mosaik 2.0 and 2.1. - *Sebastian Rohjans* and *Sebastian Lehnhoff* accompanied mosaik's development as group and scientific leaders. They also put lots of effort into making mosaik open-source software. - *Okko Nannen* and *Florian Schlögl* joined the team in May / July 2014. We'd also like to thank everyone who worked with mosaik and gave us feedback to make it better.
