Lovelock, JamesEphraim

Lovelock, JamesEphraim (b. 1919)A British chemist, biophysicist, inventor, and principal author of the Gaia hypothesis, the development of which began in the 1960s, while he was working at the Jet Propulsion Laboratory in Pasadena, California, designing instruments in connection with the NASA lunar and Mars programmes. Earlier he invented the electron capture detector, an instrument capable of measuring extremely small amounts of substances (e.g. pesticide residues, methyl mercury, tetraethyl lead, polychlorinated biphenyls (PCBs), chlorofluorocarbons (CFCs), and nitrous oxide) in the natural environment. During the 1972–3 voyage of the research ship Shackleton, Lovelock used the electron capture detector to discover the global distribution of CFCs, dimethyl sulphide, methyl iodide, and carbon disulphide. In collaboration with R. J. Charlson, M. O. Andreae, and S. G. Warren, he hypothesized a link between marine algae and cloud formation that is now accepted by meteorologists and for which the four were awarded the Norbert Gerbier Prize and Medal of the World Meteorological Organization in 1988. He was elected a Fellow of the Royal Society in 1974 and received a CBE in 1989. For his contributions to environmental science Lovelock was awarded the Amsterdam Prize of the Netherlands Royal Academy in 1990. From 1987 to 1991 he was president of the Marine Biological Association.

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.
