This chapter is a historical sketch of "time in quantum mechanics". We have adopted a "physicist's approach" to history, summarizing in rough chronological order some of the contributions underlying the topics and concepts treated in the book. The account is complemented with comments on later or recent repercussions of the original works, giving certain prominence to some of our own contributions. The time span of this "story" is almost 100 years, so necessarily many of the comments and references will be minimal, and even entire fields are absent, in particular those not related to the topics addressed in the subsequent chapters.
