Yelena Bonner (Russian: Елена Георгиевна Боннэр; 15 February 1923 – 18 June 2011) was a human rights activist in the former Soviet Union and wife of the noted physicist and dissident Andrei Sakharov. During her decades as a dissident, Bonner was noted for her characteristic blunt honesty and courage.

Bonner was born Lusik Georgievna Alikhanova in Merv, Turkmen SSR, USSR (now Mary, Turkmenistan). Her father, Georgy Alikhanov (Armenian name Gevork Alikhanyan), was an Armenian who founded the Soviet Armenian Communist Party, and was a highly placed member of the Comintern; her mother, Ruf, (Ruth Bonner), was a Jewish Communist activist. She had a younger brother, Igor, who became a career naval officer.

In 1937, Bonner's father was arrested by the NKVD and executed as part of Stalin's Great Purge; her mother was arrested a few days later, and served eight years in a forced labor camp near Karaganda, Kazakhstan, followed by nine years of internal exile. Bonner's 41-year-old maternal uncle, Matvei Bonner, was also executed during the purge, and his wife internally exiled. All four were exonerated (rehabilitated) following Stalin's death in 1953. Serving as a nurse during World War II, Bonner was wounded twice, and in 1946 was honorably discharged as a disabled veteran. After the war she earned a degree in pediatrics from the First Leningrad Medical Institute.

George Wald (November 18, 1906 – April 12, 1997) was an American scientist who is best known for his work with pigments in the retina. He won a share of the 1967 Nobel Prize in Physiology or Medicine with Haldan Keffer Hartline and Ragnar Granit.

As a postdoctoral researcher, Wald discovered that vitamin A was a component of the retina. His further experiments showed that when the pigment rhodopsin was exposed to light, it yielded the protein opsin and a compound containing vitamin A. This suggested that vitamin A was essential in retinal function.

In the 1950s, Wald and his colleagues used chemical methods to extract pigments from the retina. Then, using a spectrophotometer, they were able to measure the light absorbance of the pigments. Since the absorbance of light by retina pigments corresponds to the wavelengths that best activate photoreceptor cells, this experiment showed the wavelengths that the eye could best detect. However, since rod cells make up most of the retina, what Wald and his colleagues were specifically measuring was the absorbance of rhodopsin, the main photopigment in rods. Later, with a technique called microspectrophotometry, he was able to measure the absorbance directly from cells, rather than from an extract of the pigments. This allowed Wald to determine the absorbance of pigments in the cone cells (Goldstein, 2001).

Andrei Dmitrievich Sakharov (Russian: Андре́й Дми́триевич Са́харов; May 21, 1921 – December 14, 1989) was a Soviet nuclear physicist, dissident and human rights activist.

He gained renown as the designer of the Soviet Union's Third Idea, a codename for Soviet development of thermonuclear weapons. Sakharov was an advocate of civil liberties and civil reforms in the Soviet Union. He was awarded the Nobel Peace Prize in 1975. The Sakharov Prize, which is awarded annually by the European Parliament for people and organizations dedicated to human rights and freedoms, is named in his honor.

Sakharov was born in Moscow on May 21, 1921. His father was Dmitri Ivanovich Sakharov, a private school physics teacher and an amateur pianist. His father later taught at the Second Moscow State University. Dmitri's grandfather Ivan had been a prominent lawyer in Tsarist Russia who had displayed respect for social awareness and humanitarian principles (including advocating the abolition of capital punishment) that would later influence his grandson. Sakharov's mother was Yekaterina Alekseyevna Sakharova (née Sofianos and of Greek ancestry). His parents and his paternal grandmother, Maria Petrovna, largely shaped Sakharov's personality. Although his paternal great-grandfather had been a priest in the Russian Orthodox Church, and his pious mother did have him baptised, his father was an atheist and religion did not play an important role in his life, though he did believe that a non-scientific "guiding principle" governed the universe and human life.

Yelena Gadzhievna Isinbayeva (Russian: Елена Гаджиевна Исинбаева, Elena Gadžievna Isinbaeva) (born 3 June 1982) is a Russian pole vaulter. She is twice an Olympic gold medalist (2004 and 2008), a five-time World Champion and the current world record holder in the event. As a result of her accomplishments, she is widely considered the greatest female pole-vaulter of all time.

Isinbayeva has been a major champion on nine occasions (Olympic, World outdoor and indoor champion and European outdoor and indoor champion). She was also the jackpot winner of the IAAF Golden League series in 2007 and 2009. After poor performances at world championships in 2009 and 2010, she took a year-long break from the sport.

She became the first woman to clear the five-metre barrier in 2005. Isinbayeva's current world records are 5.06 m outdoors, a record Isinbayeva set in Zurich in August 2009, and 5.01 m indoors, a record set in February 2012. The latter was Isinbayeva's twenty-eighth pole vault world record.

Isinbayeva was named Female Athlete of the Year by the IAAF in 2004, 2005 and 2008, and World Sportswoman of the Year by Laureus in 2007 and 2009. She was given the Prince of Asturias Award for Sports in 2009. She is one of only seven athletes (along with Valerie Adams, Usain Bolt, Veronica Campbell-Brown, Jacques Freitag, Jana Pittman, Dani Samuels) to win world championships at the youth, junior, and senior level of an athletic event.
