Margreet de Heer lives and works in Amsterdam, The Netherlands, with her husband Yiri T. Kohl.
A long time ago, she studied Theology at the University of Amsterdam, but through divine intervention she ended up as a comic artist. She worked at the famous comic store Lambiek from 2000 until 2005, and wrote a book about Dutch comics together with Kees Kousemaker.
Since 2005 she is a full-time comic artist producing a wide range of work, from children's comics in magazines to cartoons at business conferences. In 2007 she started making philosophical comic "reports" for newspaper Trouw. This resulted in a book edition in 2010, soon followed by graphic novels about Religion, Science and World Domination. Margreet plans to expand the series to a total of seven books, also covering the subjects Love, Death and Self.
'Philosophy: a Discovery in Comics' and 'Science: a Discovery in Comics' are successfully published at NBM. 'Religion: a Discovery in Comics' came out in October 2015.
