LOST TIME: WHEN GIANTS ROAMED THE EARTH

Some after-dinner thoughts on the giants of infrared space astronomy. I here describe important events in infrared astronomy starting from 1964 when I started working on my PhD. Here I describe how I became involved in IRAS, Infrared Space Observatrory (ISO), Herschel , Spitzer and AKARI, together with important events that led to these great missions.
