In the late 1800s, Greek women like Sevasti Kallisperi could only go to school to learn domestic skills like managing a home. Girls' classes were shorter than boys', and diplomas allowed a narrow range of job opportunities. Kallisperi hired a private tutor so her education could match the boys but was still denied entry to Athens University (even though she passed the entrance exams). When appeals failed, she went all the way to Paris for her education, returning in 1891 as the first Greek woman to earn a university degree. She would also become Greece's first university-trained female teacher.

The film Toy Story 2 was nearly lost in 1998 when an animator accidentally deleted 90% of its assets from Pixar's internal servers. The associate technical director was among the first to notice as character models disappeared from their works in progress.

The Pixar team was able to recover nearly all of the lost assets save for a few recent days of work, allowing the film to proceed.
