“When the maids are beautiful and the concubines charming, this is not a blessing,” warns Confucian master Zhu Bolu in a seventeenth-century work of household advice. “For servants,” his next maxim advises, “don’t employ handsome boys.”

May 1 was codifed in 1820 as the date housing contracts in New York City expired or were renewed. Davy Crockett witnessed moving day in 1834. “It seemed a kind of frolic, as if they were changing houses just for fun,” he wrote. “Every street was crowded with carts, drays, and people. So the world goes. It would take a good deal to get me out of my log house, but here, I understand, many persons ‘move’ every year.” 

Analytic philosopher Ludwig Wittgenstein was asked in 1926 by his youngest sister to help plan her new house. He quickly became obsessed, taking a year to design the door handles, another for the radiators. Near the project’s completion, he demanded the ceiling be raised thirty millimeters to achieve his desired proportions. “It seemed indeed to be much more a dwelling for the gods,” wrote another Wittgenstein sister, “than for a small mortal like me.”

Harington was banished from court for the pamphlet but allowed back in 1598, when he installed a water closet in the queen’s Richmond palace.
