“My spiritual pain is unbearable...”

Among the displays of assault rifles at the Mikhail Kalashnikov Museum in Izhevsk is a small lawnmower Kalashnikov designed to push about the grounds of his summer cottage. It is said that Mikhail Kalashnikov loved to care for his grass. Kalashnikov gave the lawnmower the same sensible qualities he gave the gun that bears his name. The lawnmower is light, simple, cheap to construct and easy to hold — something a child could use.

Kalashnikov didn’t regret inventing the Kalashnikov rifle. “I invented it for the protection of the Motherland,” he said.  Still, he once mused that he would like to have been known as a man who helped farmers and gardeners. “I wanted to invent an engine that could run forever,” Kalashnikov once said. “I could have developed a new train, had I stayed in the railway.” But this was not to be.

Serendipitous explorer of the clitoris and developer of the condom.

 

Not long after the Renaissance doctor Gabriello Fallopio invented a silk prototype for the condom in 1564 (see “Columbus Discovers the Clitoris”), European men-about-town took to wearing so-called “gold-beater skins” woven from the dried intestines of sheep, calves, and horses. The learned scholar H. M. Hines speculates that it was a slaughterhouse worker who first came up with this technological advance, aiming for a more durable yet still sensitive sheath. The finest quality examples, produced by skilled Italian artisans, were hand-sewn at one end and tied by an elegant ribbon at the other; they were wickedly expensive, but could be washed, dried, and reused.

Acceptance of the invention was slow all over Europe. In 1671, the French noblewoman Madame de Sévigné warned her daughter that condoms were worse than useless in the bedroom, “armour against enjoyment, and… More…
