Editing Ignition magneto (section)

== History ==
In the late 1890s, English engineer [[Frederick Richard Simms]] collaborated with the German engineer [[Robert Bosch]], and his staff of Arnold Zähringer, Young Rall, and Gottlob Honold, in developing the first practical high-tension magneto. In 1900, the Bosch magneto ignition was used in the [[Gottlieb Daimler]] engines on the [[Zeppelin]].<ref>{{cite book | last = Kohli | first = P.L. | title = Automotive Electrical Equipment | publisher = Tata McGraw-Hill | year = 1993 |isbn = 0-07-460216-0}}</ref><ref name="rb">{{cite book |last1=Heuss |first1=Theodor |title=Robert Bosch: His Life and Achievements |date=1994 |publisher=Henry Holt and Company |location=New York |isbn=0805030670 |pages=102-107,124-126}}</ref>

The first car to use magneto ignition was the 1901 German [[Mercedes 35 hp]] racing car, followed by various cars produced by [[Benz & Cie.|Benz]], [[Mors (automobile)|Mors]], [[Turcat-Mery]], and [[Nesseldorf]].<ref name="Georgano, 1985" >{{Cite book |last=Georgano |first=G.N. |author-link=G.N.
