question: Who was born in 1868 and performed the oil drop experiment?
answer: Robert Andrews Millikan
context: Title: Pitch drop experiment
  Passage: The pitch drop experiment is a long-term experiment that measures the flow of a piece of pitch over many years.  Pitch is the name for any of a number of highly viscous liquids that appear solid, most commonly bitumen.  At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
  Title: Francis Ernest Lloyd
  Passage: Francis Ernest Lloyd (October 4, 1868 – October 10, 1947) was an American botanist, born in Manchester, England, and educated at Princeton University (A.B., 1891; A.M., 1895), in New Jersey, and in Europe at Munich and Bonn, in Germany.  He was employed at various institutions of higher learning from 1891 onward.  He served on the faculties of Williams College, Pacific University, Teachers College (Columbia University), Harvard Summer School, Alabama Polytechnic Institute (professor of botany, 1906-1912), and at McGill University, in Montreal, Canada after 1912.  Professor Lloyd had worked as an investigator in the Desert Botanical Laboratory of the Carnegie Institution in 1906 and as cytologist of the Arizona Experiment Station in 1907.  He edited "The Plant World" from 1905 to 1908, and was co-author of "The Teaching of Biology in the Secondary Schools" (1904; second edition, 1914).  Professor Lloyd wrote:
  Title: Egg drop competition
  Passage: The egg drop contest is an experiment usually performed by college or primary school students.  Competitors typically attempt to create a device that can keep a raw chicken egg intact when dropped from a height.  Students are asked to build a device made from a limited amount of materials to support an egg when dropped from various heights.
  Title: Electrostatic levitation
  Passage: Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity.  It was used, for instance, in Robert Millikan's oil drop experiment and is used to suspend the gyroscopes in Gravity Probe B during launch.
  Title: Bisporella citrina
  Passage: Bisporella citrina, commonly known as yellow fairy cups or lemon discos, is a species of fungus in the family Helotiaceae.  The fungus produces tiny yellow cups up to 3 mm in diameter, often without stalks, that fruit in groups or dense clusters on decaying deciduous wood that has lost its bark.  The widely distributed species is found in North Africa, Asia, Europe, North America, and Central and South America.  Found in late summer and autumn, the fungus is fairly common, but is easily overlooked owing to its small size.  There are several similar species that can in most cases be distinguished by differences in color, morphology, or substrate.  Microscopically, "B. citrina" can be distinguished from these lookalikes by its elliptical spores, which have a central partition, and an oil drop at each end.
  Title: Alec (Alirza) Rasizade
  Passage: Alec (Alirza) Rasizade (born in 1947) is a retired American professor of history and political science, who specialized in Sovietology, primarily known for the typological model, which describes the impact of a drop in oil revenues on the process of decline in rentier states by stages and cycles of their general socio-economic degradation upon the end of an oil boom.  He has also authored more than 200 studies on the history of international relations in the 20th century, Perestroika reforms and breakup of the USSR, oil diplomacy and contemporary politics in the post-Soviet states and autonomies of Russia, Central Asia and the Caucasus.
  Title: Annie Hindle
  Passage: Annie Hindle was the first popular male impersonator performer in the United States.  Born in the 1840s in England, she and her adoptive mother, Ann Hindle, migrated to New York City in 1868.  Hall performed as a male impersonator in solo acts and in minstrel shows from 1868 to 1886.
  Title: Clavulina
  Passage: Clavulina is a genus of fungi in the family Clavulinaceae, in the Cantharelloid clade (order Cantharellales). .  Species are characterized by having extensively branched fruit bodies, white spore print, and bisterigmate basidia (often with secondary septation).  Branches cylindrical or flattened, blunt, pointed or crested at apex.  Hyphae with or without clamps.  Basidia cylindrical to narrowly clavate, mostly with two sterigmata which are large and strongly incurved.  Spores subspherical or broadly ellipsoid, smooth, thin-walled, each with one large oil drop or guttule.  The genus contains approximately 45 species with a worldwide distribution, primarily in tropical regions.  Species of "Clavulina" are mostly ectomycorrhizal.  A recent study has identified Clavulina to the genera level as present on "Nothofagus menziesii" adventitious roots
  Title: Oil drop experiment
  Passage: The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron).
  Title: Robert Andrews Millikan
  Passage: Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electronic charge and for his work on the photoelectric effect.
