Passage: Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.

Passage: Five-time world champion Sébastien Ogier was the fastest man to finish the day other than the defending rally winner Ott Tänak, who set five out of six fastest stage times and built a 12.3-second lead over the Frenchman, while championship leader Thierry Neuville was another 15.1 seconds behind. Elfyn Evans climbed up three places in the afternoon loop and edged Jari-Matti Latvala by a second. Dani Sordo completed the day in sixth, only one-tenth of a second ahead of Esapekka Lappi, who failed to come to terms with dirt dragged onto the roads by the early starters. Craig Breen lost some time due to being caught in a heavy rain shower in the early stage in the eighth place, followed by Andreas Mikkelsen, who was struggling with his i20's handling and chose to change his driving style, in ninth, only one second behind. Teemu Suninen, driving a third Fiesta, in tenth. Lacking of power caused Mads Østberg to fail to find the pace like Finland, which made him cleared the day off the leaderboard in eleventh overall.

Passage: Blignaut went to the State School in his birthplace Paarl, where he subsequently attended the Gymnasium (Grammar School). After his exams Blignaut went to Cape Town, where he joined the colonial administration. In 1861 he passed the examination for the State Service Certificate of the Cape Colony and in 1862 he moved to the Orange Free State. Here he was appointed to the position of clerk to the Landdrost and Justice of the Peace of Philippolis (17 September 1862). At the time, civil, judicial, and military administration were still very much in the same hand. In view of Basotho threats, President Brand ordered the reorganisation of the Orange Free State defence, and the formulation of clear regulations for the different Volunteer Corps, which were administered by the Landdrosts' offices. For Philippolis Blignaut and J.G. Fraser attended the conference.
