William Otis (1813–1839) was an American inventor of the steam shovel. Otis received a patent for his creation on February 24, 1839.

In 1839, William Smith Otis, civil engineer of Philadelphia, Pennsylvania, was issued a US patent for the steam shovel (No. 1,089) for excavating and (removing earth). Officially the patent drawing is missing but a drawing exists which is said to be the one from the patent[1] and this shows the crane mounted on a railroad car. A load of earth could be lifted by the bucket, raised by the crane and turned to be dumped, such as in railcars. The patent described how a steam engine of a type then in ordinary use, was installed with a power control mechanism for the crane, and a system of pulleys to move its arms and bucket. It could move about 380 cubic meters of earth a day, with its 1.1 cubic meter capacity shovel and 180° slewing wooden jib. It was first used on the Western Railroad in Massachusetts.

William Smith Otis was born on September 20, 1813, in Pelham, Massachusetts, and was cousin to Elisha Otis of elevator fame. At an early age, William was interested in earthworks and mechanics. At the age of 22, he had shown an uncommon mechanical ingenuity and created the first steam powered mechanical excavator.

Using materials obtained in vicinity of Canton, Massachusetts, William created the machine in 1835 which was used building railroad lines between Norwich and Worcester. Working with the company, ”Carmichael and Fairbanks”, William Smith Otis devised an apparatus carrying out the same actions as the person with a shovel.

Otis moved to Philadelphia and enlisted the talents of Joseph Harrison to help construct a prototype. Harrison operated the company ”Garrett and Eastwick," and fabricated a pre-production model in 1836. On June 15, 1836, William Smith Otis received the patent for the invention; however during a fire, the engineering specifications had been destroyed.

On February 24, 1839, the patent behind number 1089 officially entered validity, and called “Crane-Excavator for Excavating and Removing Earth”.

William Smith Otis died on November 13, 1839 at the age of 26.
