William Henry Johnson (c. 1857 or c. 1842[nb 1] – April 9, 1926), known as Zip the Pinhead, was an American freak show performer known for his tapered head.

His tapering cranium and heavy jaw made him attractive to agents from van Emburgh's Circus in Somerville, New Jersey.

A furry suit was made to fit him, and his hair was shaped to a tiny point that further accented his sloping brow.

It was further explained that the "wild man", the "What-Is-It", subsisted on raw meat, nuts, and fruit, but was learning to eat more civilized fare such as bread and cake.

He shared the stage with other anomalies, including his friends "Texas Giant" Jim Tarver, "Tallest Man in the World" Jack Earle and Koo-Koo the Bird Girl.

In 1860, he was visited at the museum by Albert Edward, the Prince of Wales; his photo was taken by Civil War photographer Mathew Brady.

[8] Zip caught bronchitis in early 1926, and despite the wishes of his doctor and Captain White, he continued to perform his part in the stage play Sunny at the New Amsterdam Theater.

Upon the closing of the play, he returned to his home in Bound Brook, New Jersey, where he was cared for by his doctor, Captain White, and his sister.
