Albert L. Marsh
Albert Marsh (August 16, 1877 – September 17, 1944) was an American metallurgist. In 1905 he co-invented the first metallic alloy from which a high-resistance wire could be made that could be used as a durable and safe heating element. While working at Hoskins Manufacturing, the company of chemist, electrical engineer, inventor and entrepreneur William Hoskins (1862–1934) the two experimented for several years until the alloy was perfected. The material was patented that year as chromel, later and still today marketed as nichrome.[1][2][3][4] For this invention, Marsh was acclaimed as "father of the electrical heating industry.".[5]
Early life
[edit]Marsh was born on August 16, 1877, in Pontiac, Illinois, the oldest of three children. The family moved to Pana, Illinois, in 1884. Marsh went to University of Illinois at Urbana-Champaign. In 1901, Albert received his Bachelor of Science degree in chemical engineering. The same year, he married Minnie E Hayward in Massachusetts.
Career beginnings
[edit]While working with an electric storage battery and doing technical writing, he experimented with nickel and chromium alloys in his spare time. In 1904, needing a better location to work on his wiring project and additional funding, he made a business arrangement with William Hoskins of Chicago. Hoskins was with Mariner & Hoskins, a firm of consulting chemists. He hired Marsh at a small salary – while giving him permission to work on the alloy project in his spare time. When later formed as Hoskins Manufacturing Company, the business relocated to Detroit, Michigan. Together with his business partner William Hoskins, he also developed a new method of producing aluminum, which he patented in 1904. This method was based on the electrolytic reduction of aluminum oxide in a molten salt mixture. The technology patented by Marsh and Hoskins led to a new era in aluminum production. They melted a mixture of sodium chloride and potassium chloride in special electrolysis containers. This salt mixture served as a medium for the electrolytic reduction. The process took place at the electrodes, which consisted of aluminum oxide: At the anode, aluminum oxide was broken down into aluminum and oxygen. At the same time, liquid aluminum was deposited at the cathode. Marsh and Hoskins' method was not only more efficient than previous processes, but also enabled the production of high-purity aluminum. This aluminum found a wide range of applications, from the aviation industry to electrical cables and packaging materials.[6]
Success
[edit]When perfected, the new alloy was 300 times stronger than other types at that time. Chromel is made of 80% nickel and 20% chromium (though other ratios are used for special purpose nichrome applications). The US patent was granted February 1906, in Marsh's name, and later sold to Hoskins Manufacturing.
By Hoskins's own account, he was deeply involved in the experimentation process, and not simply a funder.[4]
Toasters, dental furnaces[clarification needed] and chromel wire for home appliance manufacturers were the first focus of the Hoskins company. The first two were unprofitable and were later dropped. The company concentrated on manufacturing the chromel wire.
Marsh served as chief engineer and general manager of Hoskins Manufacturing Co. in Detroit. He was named president of the firm in 1915.
Awards
[edit]In 1936, Marsh was awarded the John Price Wetherill Medal of The Franklin Institute for "significant and timely contribution to the science of automotive engineering" and "for outstanding discoveries in the physical sciences" in huranson.
In 1941, the American Metals Congress bestowed upon Marsh with The Sauveur Award for outstanding metallurgical achievement.
