About the J. Lawrence Smith Medal

The J. Lawrence Smith Medal is awarded every three years for investigations of meteoric bodies. The award includes a $50,000 prize. The award was established as a gift from Sarah Julia Smith in memory of her husband and has been presented since 1888.

Most Recent Recipient

Kevin D. McKeegan, University of California, Los Angeles, will receive the 2018 J. Lawrence Smith Medal.

McKeegan is a world-recognized leader in the application of micro-analytical techniques to study meteoritic materials — incredibly precise research which has improved our understanding of the processes and chronology of the early solar system. Read more about McKeegan's work»


Kevin D. McKeegan (2018)
For contributions to understanding of the processes and chronology of the early solar system as recorded by primitive meteorites, for innovation in analytical instrumentation, and for showing that the oxygen isotopic compositions of the Earth and rocky planets and meteorites are distinctly different from that of the Sun.

Hiroko Nagahara (2015)
For her work on the kinetics of evaporation and condensation processes in the early Solar System and her fundamental contributions to one of the most enduring mysteries in meteoritics, the formation of the chondrules that constitute the characteristic component of the most abundant group of meteorites.

Harry Y. McSween, Jr. (2012)
For his studies of the igneous and metamorphic histories of the parent planets of the chondritic and achondritic meteorites, with particular emphasis on his work on the geological history of Mars based on studies of Martian meteorites and spacecraft missions to this planet.

Robert N. Clayton (2009)
For pioneering the study of oxygen isotopes to unravel the nature and origin of meteorites, showing that meteorites were assembled from components with distinct nuclear origins.

Klaus Keil (2006)
For his pioneering quantitative studies of minerals in meteorites and important contributions to understanding the nature, origin, and evolution of their parent bodies.

John T. Wasson (2003)
For important studies on the classification, origin, and early history of iron meteorites and chondritic meteorites, and on the mode of formation of chondrules.

George W. Wetherill (2000)
For his unique contributions to the cosmochronology of the planets and meteorites and to the orbital dynamics and formation of solar system bodies.

Ernst Zinner (1997)
For his pioneering studies of the isotopic composition of circumstellar dust grains preserved in meteorites, opening a new window to the formation of the solar nebula.
