There are many examples of plagiarism. One of the more famous examples is when psychologist and tenured professor René Diekstra was accused of scientific plagiarism in a section in one of his science books. In 1997 when this happened, there wasn’t a solid universal definition of plagiarism, which complicated the lawsuit. Even without a concrete definition though, duplicating another’s work was not something taken lightly, and as a result, he had to step down from his position.
