When same-sex civil unions were accepted by Norwegian law in 1993, Lowzow and her partner, author and activist Karen-Christine Friele, were among the first to formalize their relationship.

Sidney David Drell was an American theoretical physicist and arms control expert.

Zdeněk Remsa was a Czech ski jumper. He competed at the 1948 Winter Olympics.

Kazuo Wada was a Japanese businessman, the effective founder and chairman of the defunct multinational supermarket and department store chain Yaohan. He took over his parents' small grocery chain in the 1950s and spent the next four decades growing Yaohan into a global company with annual sales of 500 billion yen at its peak. However, Yaohan was unable to sustain its heavy loss and debt burden during the 1997 Asian financial crisis and declared bankruptcy.

Barbara McClintock was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927. There she started her career as the leader in the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information. She was recognized as among the best in the field, awarded prestigious fellowships, and elected a member of the National Academy of Sciences in 1944.

Louise Marie Zibold Reiss was an American physician who coordinated what became known as the Baby Tooth Survey, in which deciduous teeth from children living in the St. Louis, Missouri area who were born in the 1950s and 1960s were collected and analyzed over a period of 12 years. The results of the survey showed that children born in 1963 had levels of strontium-90 in their teeth that were 50 times higher than those found in children born in 1950, before the advent of widespread nuclear weapons testing. The findings helped convince U.S. President John F. Kennedy to sign the Partial Nuclear Test Ban Treaty with the United Kingdom and Soviet Union, which ended the above-ground testing of nuclear weapons that placed the greatest amounts of nuclear fallout into the atmosphere.
