Manvel "Manny" Gamburyan (Armenian: Մանվել Գամբուրյան ; born May 8, 1981) is a retired Armenian-American fighter who competed in the UFC's Bantamweight and Featherweight divisions.
 A professional competitor since 1999, he was a cast member of Spike TV's The Ultimate Fighter 5, and also competed in the WEC and for King of the Cage.
Louis Alexander Slotin (1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who worked on the Manhattan Project.
 During World War II, Slotin conducted research at Los Alamos National Laboratory.
 He performed experiments with uranium and plutonium cores to determine their critical mass values.
 On 21 May 1946, Slotin was conducting a demonstration when he accidentally initiated a fission reaction, which released a burst of hard radiation.
 He received a lethal dose of radiation and died of acute radiation syndrome nine days later.
 Slotin was the second person to die from a criticality accident, following the death of Harry Daghlian, who had been exposed to radiation by the same core that killed Slotin.
 Slotin was publicly hailed as a hero by the United States government for reacting quickly and preventing his accident from killing any colleagues.
 He was later criticized for failing to follow protocol during the experiment.
In Greek mythology, Despoina, Despoena or Despoine, was the daughter of Demeter and Poseidon and sister of Arion.
 She was the goddess of mysteries of Arcadian cults worshipped under the title "Despoina", "the mistress" alongside her mother Demeter, one of the goddesses of the Eleusinian mysteries.
 Her real name could not be revealed to anyone except those initiated to her mysteries.
 Pausanias spoke of Demeter as having two daughters; Kore being born first, then later Despoina.
 With Zeus being the father of Kore, and Poseidon as the father of Despoina.
 Pausanias made it clear that Kore is Persephone, though he wouldn't reveal Despoina's proper name.
The demon core was a 6.2 kg subcritical mass of plutonium measuring 89 mm in diameter, roughly the size of a softball, best known for its involvement in two criticality accidents.
 The core was slated for use in a third World War II nuclear bomb, but remained in use for testing after Japan's surrender.
 It was designed with a small safety margin to ensure a successful explosion of the bomb.
 The device briefly went supercritical when it was accidentally placed in supercritical configurations during two separate experiments intended to guarantee the core was indeed close to the critical point.
 The incidents happened at the Los Alamos laboratory in 1945 and 1946, and resulted in the acute radiation poisoning and subsequent deaths of scientists Harry Daghlian and Louis Slotin.
 After these incidents the spherical plutonium core was referred to as the "demon core".
Professor Wale Adebanwi, (born 1969), is a Nigerian - born first Black African Rhodes Professor at Oxford University
The 1940 United States Senate election in Missouri was held on November 5, 1940.
 Incumbent Democratic U.S. Senator and future President of the United States Harry S. Truman, who was first elected in 1934, decided to seek re-election to a second term.
 He narrowly defeated Republican nominee Manvel H. Davis.
Augustine of Canterbury (born first third of the 6th century – died probably 26 May 604) was a Catholic Benedictine monk who became the first Archbishop of Canterbury in the year 597.
 He is considered the "Apostle to the English" and a founder of the Catholic Church in England.
Haroutune Krikor "Harry" Daghlian Jr. (May 4, 1921 – September 15, 1945) was a physicist with the Manhattan Project which designed and produced the atomic bombs that were used in World War II.
 He accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site of the Los Alamos Laboratory in New Mexico, resulting in his death 25 days later.
"Lab Rats", also known as "Lab Rats: Bionic Island" for its fourth season, is an American television sitcom that premiered on February 27, 2012, on Disney XD.
 It focuses on the life of teenager Leo Dooley, whose mother, Tasha, marries billionaire genius Donald Davenport.
 He meets Adam, Bree, and Chase, three bionic superhumans, with whom he develops an immediate friendship.
 It should be noted that the names of the Lab Rats imply that they were originally known as subjects A, B, C and D. Adam was born first, then Bree, then Chase, and finally Daniel.
Karen Darabedyan (born December 18, 1986) is an Armenian professional mixed martial artist.
 He is best known for fighting in WEC's lightweight division.
 He is a training partner of Karo Parisyan and Manvel Gamburyan.
 He had a 12-0 amateur boxing record before he began MMA.

Question: Who was born first, Manvel Gamburyan or Harry Daghlian?
Answer: Haroutune Krikor "Harry" Daghlian Jr.
