MARCUS, SIEGFRIED (1831–1898), German inventor, born in Malchin. Marcus joined the Berlin engineering firm of Siemens und Halske in 1848 and worked on the establishment of telegraphic communication between Berlin and Magdeburg. In 1852 he settled in Vienna, where from 1860 he had his own laboratory. In 1864 he patented a petrol-driven automobile. A car he built in 1875 was preserved in the Vienna Industrial Museum. His patents included an electric lamp (1877), telegraphic relays, a microphone, a loudspeaker, electric fuses for submarine mines, and other devices which were developed by others in later years.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
