"Land was legendary for his eccentric and exhausting work habits, which dated back to his Harvard days. Like the proverbial mad scientist, when Land was immersed in a project, he would lock himself in the lab for days on end, stopping only long enough to eat and often not bothering to change clothes. When he was on one of these jags, Land's assistants would be scheduled in shifts to keep up with him since they had a tendency to fold at the knees without sleep."
