William Samuel Henson

William Samuel Henson (3 May 1812[1][2] - 1888) was a pre-Wright brothers aviation engineer and inventor.

Henson was born in Nottingham, England. Henson was involved in lace-making in Chard[3] and he obtained a patent on improved lace-making machines in 1835. Henson is best known as an early pioneer in aviation, but patented many other inventions, some of which are in wide use today.[4]

Aeronautical inventions

Starting c. 1838, Henson became interested in aviation. In April 1841 he patented an improved lightweight steam engine, and with fellow lacemaking-engineer John Stringfellow in c. 1842 he designed a large passenger-carrying steam-powered monoplane, with a wing span of 150 feet, which he named the "Henson Aerial Steam Carriage". He received a patent on it in 1843 along with Stringfellow.

Henson, Stringfellow, Frederick Marriott, and D.E. Colombine, incorporated as the Aerial Transit Company in 1843 in England, with the intention of raising money to construct the flying machine. Henson built a scale model of his design, which made one tentative steam-powered "hop" as it lifted, or bounced, off its guide wire. Attempts were made to fly the small model, and a larger model with a 20-foot wing span, between 1844 and 1847, without success.

Henson grew discouraged, married and emigrated in 1849 to the United States, while Stringfellow continued to experiment with aviation.

Henson appeared as a character in a fictional newspaper story by Edgar Allan Poe, which recounted a supposed trans-Atlantic balloon trip, in which Henson was one of the passengers on the balloon.[5]

Henson and Stringfellow are frequently mentioned in books on the history of aviation.[6] The Royal Aeronautical Society holds annual "Henson-Stringfellow" lectures; as of 2008 they have held 52. A glacier in Antarctica is named after him due to his work in aviation (Henson Glacier: 64'06'S, 60'11'W[7]).

Aerial Design

The Aerial's wings were rectangular, and were formed by wooden spars covered with fabric, and braced, internally and externally, with wires. The Aerial Steam Carriage was to be powered by two contra-rotating six-bladed propellers mounted in the rear in a push-type system. The design follows earlier "birdlike" gliders, and the ideas of George Cayley, and Henson corresponded with Cayley in an attempt to obtain funding after the efforts to obtain the support of Parliament and sell stock failed.[8] The Aerial Transit Company never built the largest version of the Aerial Steam Carriage because of the failed attempts with the medium-sized model. Henson, Stringfellow, Marriott and Colombine dissolved the company around 1848.

Advertising

The Aerial Transit Company's publicist, Frederick Marriott, commissioned prints in 1843 depicting the Aerial Steam Carriage over the pyramids of Egypt, in India, and over London, England, and other places, which drew considerable interest from the public. The prints have appeared on several stamps of various countries. Marriott later became himself an aviation pioneer in California.

Other inventions and innovations

Henson obtained a number of patents in widely varying areas. Major patents include:

Henson invented the modern form of the razor, the 'T' shaped safety razor, and patented it in 1847: "the cutting blade of which is at right angles with the handle, and resembles somewhat the form of a common hoe."[9] While a major improvement on the previous form of safety razor, an additional improvement was needed to make safety razors common. In 1901, Gillette combined Henson's T-shaped safety razor with disposable blades, and produced the modern razor.[10]

Henson published a pamphlet on astronomy in 1871 suggesting that the solar system formed from cold dust and gas, and discussed how it could condense into meteors and comets, and further condense into planets, moons and the sun, in the process heating up. He also discusses how this would lead to the planets orbiting in the ecliptic and rotating in the same general plane.[11]

Henson created inventions in other areas as well. Among them were ice-making machines (1870), fabric waterproofing, and cistern-cleaning.[12] He patented and submitted a proposal for an improved low-recoil breech-loading cannon design to the US Navy in 1861; it was rejected as impractical.[13]

Emigration and life in the United States

In 1849 William Henson and his wife, Sarah, left England and moved to the United States, joining his father and settling in Newark, New Jersey. Henson never did any further aviation research while in the United States and worked as a machinist, civil engineer and inventor.[14][15] He had 7 children, only 4 of whom lived to adulthood.

Henson died in 1888 in Newark. He and most of his family were buried in East Orange, New Jersey.
