During William McKinley's tenure as president he developed a specific handshake known as "McKinley Grip."
He would warmly greet each recipient and offer his right hand, give a firm pump, and then quickly yank his hand away before the other party could reciprocate.
All the while, his left hand would clasp the person's elbow, and give them a friendly but vigorous shake.
The McKinley grip was ideal for greeting the thousands of Americans he would meet face to face during his tragically short tenure as president.
As fate would have it, on September 6, 1901, a man approached McKinley for a routine handshake, McKinley noticed the man's right hand was bandaged and quickly offered his left hand to compensate.
At that time the man drew a pistol and shot the president. Within a few days McKinley died of the gunshot wound sustained while offering up his signature handshake.
