Beryl May Dent (10 May 1900 – 9 August 1977) was a British mathematical physicist, technical librarian, and a programmer of early analogue and digital computers to solve electrical engineering problems. A graduate of the University of Bristol, Dent wrote her master's thesis on the forces between atoms and ions, with the objective of calculating theoretically the properties of carbonate and nitrate crystals. Later work has shown that the results she obtained had direct application to atomic force microscopy by predicting that non-contact imaging is possible only at small tip-sample separations. In 1930, she joined Metropolitan-Vickers Electrical Company Ltd, Manchester, as a technical librarian for the scientific and technical staff of the research department. She contributed to papers on numerical methods for solving differential equations by the use of the differential analyser that was built for the University of Manchester and Douglas Hartree. She was the first to develop a detailed reduced major axis method for the best fit of a series of data points. Later in her career she became leader of the computation section at Metropolitan-Vickers, and then a supervisor in the research department for the section that was investigating semiconducting materials.

Anodorhynchus is a genus of large blue macaws from open and semi-open habitats in central and eastern South America. It includes two extant species, the hyacinth macaw and Lear's macaw also known as the indigo macaw, and one probably extinct species, the glaucous macaw. At about 100 centimetres (39 in) in length the hyacinth macaw is the longest parrot in the world. Glaucous and Lear's macaws are exclusively cliff nesters; hyacinth macaws are mostly tree nesters. The three species mainly feed on the nuts from a few species of palms (notably Acrocomia aculeata, Attalea phalerata, Butia yatay and Syagrus coronata). While blue macaws have been known from taxidermic and captive specimens since at least 1790, location of the Lear's macaw's endemic habitat wasn't known until 1978. The glaucous macaw was extirpated in the 1800s by clearance for agriculture and cattle grazing of the yatay palm (Butia yatay) groves upon which it fed, though rumors of its continued existence persist. Lear's macaws have made a comeback from near extinction in the early 1980s (about 60 birds) to over 1000 as a result of conservation programs. Hyacinth macaws remain locally common within parts of their range, but their range has become fragmented into three known distinct populations in southern Brazil, eastern Bolivia and northeastern Paraguay; populations are declining due to extensive trapping for the pet trade as well as habitat loss. Today the Hyacinth macaw is extinct in most of its original distribution sites. Both hyacinth and Lear's macaws are listed on CITES Appendix 1.

Shri Vyankatesh Bapuji Ketkar (18 January 1854 – 3 August 1930) was a scholar, astronomist and astrologist from Maharashtra, India. This forgotten star from the field of Indian astronomy, the legendary 'Jyotirvid' born in 1854, dedicated his life for the research and purification of Indian almanac system (Pañcānga) of timekeeping. It is a lesser known fact that he predicted the existence of 'Pluto' in 1911; even before its discovery in 1930. He authored a number of books on astronomy, Pañcānga and literature and also published many research papers in European science journals.

Sher Mohammad Marri (Balochi: میر شير محمد مری‎) was a Militant Marri Baloch tribe. He was the early leader of the Parari movement which. A Marxist, he had close ties with the leftist governments in Kabul and Moscow. Sher Muhammad Marri was born in Kohlu, Balochistan, British Raj in 1935. He was also known as Babu Shero, Shero Marri, General Sherof and Baloch Tiger.

Mary Nolan (born Mary Imogene Robertson; December 18, 1902 – October 31, 1948) was an American stage and film actress, singer and dancer. She began her career as a Ziegfeld girl in the 1920s performing under the stage name Imogene "Bubbles" Wilson. She was fired from the Ziegfeld Follies in 1924 for her involvement in a tumultuous, highly publicized affair with comedian Frank Tinney. She left the United States shortly thereafter and began making films in Germany. She appeared in seventeen German films from 1925 to 1927 using the stage name Imogene Robertson.

Upon returning to the United States in 1927, she attempted to break from her previous scandal-ridden past and adopted the stage name Mary Nolan. She was signed to Universal Pictures in 1928 where she found some success in films. By the 1930s, her acting career began to decline due to her drug abuse and reputation for being temperamental. After being bought out of contract with Universal, she was unable to secure film work with any major studios. Nolan spent the remainder of her acting career appearing in roles in low-budget films for independent studios. She made her final film appearance in 1933. After her film career ended, Nolan appeared in vaudeville and performed in nightclubs and roadhouses around the United States. Her later years were plagued by drug problems and frequent hospitalizations. She returned to Hollywood in 1939, spent her remaining years living in obscurity, then died of a barbiturate overdose in 1948.
