Oh yeah, there are plenty of such cases! I was always surprised that even famous authors, scientists and politicians managed to get caught plagiarizing. Here https://www.customwritings.com/blog/fam … cases.html there is a selection of famous plagiarism cases - really informative! For example, one of the most high-profile cases is the scandal with Joe Biden, when he was still a candidate for US President in the 80s. He used part of a speech by a British politician without specifying the source, and this was a huge blow to his campaign. Or here is the case with historian Doris Kearns Goodwin, who included entire paragraphs from other people's works in her book. Interestingly, some of them were able to justify themselves, while others completely ruined their reputations.
