An avowed eclipse chaser, he best is known for having traveled around the world to see 26 total solar eclipses since 1954.[1][2] He is also regarded as having spent more time in totality, the darkest area within the moon's umbra during a total solar eclipse, than anyone else alive.[2][3] EducationLiebenberg attended the University of Wisconsin as a physics major in the early 1950s.[1] He holds three degrees, including a PhD, from his alma mater.[7] Career and eclipsesLiebenberg witnessed his first total solar eclipse on June 30, 1954, in Mellen, Wisconsin.[4] Since then, he has traveled around the world to see solar eclipses, witnessing a total of 26 total solar eclipses. Most recently, he was planning to watch the solar eclipse of August 21, 2017, which would mark his 27th, from his driveway; by coincidence, his house in Salem, South Carolina, was located in the path of totality.[1][4][11] His primary motivation for pursuing solar eclipses has been to study the sun's corona.[1] To this end, he wrote a proposal and obtained a grant from the National Science Foundation in 1954.[4] He later worked for the Los Alamos National Laboratory carrying out research into the temperature and energy input of the corona.[1][4] In 1973, Liebenberg successfully petitioned French officials to commission an early Concorde supersonic aircraft for use in observing the solar eclipse of June 30, 1973.[11] Flying on the Concorde, a group of scientists from Los Alamos and the Paris Observarory, including Liebenberg, remained in the path of totality for 74 minutes while conducting various scientific measurements of the corona.[1][2][4][5] For comparison, the theoretical maximum duration for totality during the third millennium for any stationary point or observer on the Earth's surface is approximately seven and a half minutes.[6] He has worked as an adjunct professor in Clemson's department of physics and astronomy since 1996.[7] Personal lifeLiebenberg and his wife Norma[8] reside in Salem, South Carolina.[1] References1. ^1 2 3 4 5 6 7 {{cite news |last1=Koren |first1=Marina |title=The King of Totality |url=https://www.theatlantic.com/science/archive/2017/08/solar-eclipse-totality/537441/ |accessdate=24 September 2018 |work=The Atlantic |date=21 August 2017}} 2. ^1 2 {{cite news |last1=Greenfieldboyce |first1=Nell |title=Go See It, Eclipse Chasers Urge.
