Problem: Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.

In 1966, The New York Times referred to him as the "Father of Biophilosophy." According to Times journalist and author Howard Taubman, "he never forgets... there is a vast amount of darkness for man to penetrate. As a biologist, he believes that his science is on the frontier of tremendous new discoveries; and as a philosopher, he is convinced that humanists and artists have joined the scientists to achieve an understanding of man in all his physical, mental and spiritual complexity. Such interchanges might lead, he would hope, to a new and important school of thinkers he would designate as biophilosophers." Salk told his cousin, Joel Kassiday, at a meeting of the Congressional Clearinghouse on the Future on Capitol Hill in 1984 that he was optimistic that ways to prevent most human and animal diseases would eventually be developed. Salk said people must be prepared to take prudent risks, since "a risk-free society would become a dead-end society" without progress.  Salk describes his "biophilosophy" as the application of a "biological, evolutionary point of view to philosophical, cultural, social and psychological problems." He went into more detail in two of his books, Man's Unfolding, and The Survival of the Wisest. In an interview in 1980, he described his thoughts on the subject, including his feeling that a sharp rise and an expected leveling off in the human population would take place and eventually bring a change in human attitudes:  "I think of biological knowledge as providing useful analogies for understanding human nature.... People think of biology in terms of such practical matters as drugs, but its contribution to knowledge about living systems and ourselves will in the future be equally important.... In the past epoch, man was concerned with death, high mortality; his attitudes were antideath, antidisease", he says. "In the future, his attitudes will be expressed in terms of prolife and prohealth. The past was dominated by death control; in the future, birth control will be more important. These changes we're observing are part of a natural order and to be expected from our capacity to adapt. It's much more important to cooperate and collaborate. We are the co-authors with nature of our destiny."  His definition of a "biophilosopher" is "Someone who draws upon the scriptures of nature, recognizing that we are the product of the process of evolution, and understands that we have become the process itself, through the emergence and evolution of our consciousness, our awareness, our capacity to imagine and anticipate the future, and to choose from among alternatives."  Just prior to his death, Salk was working on a new book along the theme of biophilosophy, privately reported to be titled Millennium of the Mind.

Did Salk collaborate with anyone else on his biophilosophies?

Problem: Virat Kohli was born on 5 November 1988 in Delhi into a Punjabi family. His father, Prem Kohli, worked as a criminal lawyer and his mother, Saroj Kohli, is a housewife. He has an elder brother, Vikash, and an elder sister, Bhavna. According to his family, when he was three-years old, Kohli would pick up a cricket bat, start swinging it and ask his father to bowl at him.

Kohli was signed up by sports agent Bunty Sajdeh of Cornerstone Sport and Entertainment after the 2008 Under-19 World Cup. Sajdeh recalls, "I didn't go after them after they became stars. In fact, I watched Virat at the 2008 ICC Under-19 World Cup in Kuala Lumpur. I was mighty impressed with his attitude and the way he was marshalling his team. He had that spark. And I told Yuvi to set up the meeting." Sajdeh manages Kohli's endorsement deals, along with those of other Indian cricketers Shikhar Dhawan, Rohit Sharma and Murali Vijay. It was reported in 2013 that Kohli's brand endorsements were worth over Rs100 crore. His bat deal with MRF is said to be the costliest deal in Indian cricket history. In 2017, he signed an eight-year endorsement deal with Puma worth about Rs110 crore, becoming the first Indian sportsperson to sign a Rs100 crore deal with a brand.  In 2014, American Appraisal estimated Kohli's brand value at US$56.4 million placing him fourth on the list of India's most valued celebrity brands. The same year, UK-based magazine SportsPro rated Kohli as the second most marketable athlete in the world behind only Lewis Hamilton, placing him above the likes of Cristiano Ronaldo, Lionel Messi and Usain Bolt. In an October 2016 report by Duff & Phelps on India's most valued celebrity brands, Kohli's brand value was estimated to be US$92 million, second only to that of Bollywood actor Shah Rukh Khan.  In 2017, Kohli was ranked 7th in the list released by Forbes as the Most Valuable Brand among athletes ahead of players like Lionel Messi, Rory McIlroy and Stephen Curry with an estimated brand value of $14.5 million.  As of September 2017, Kohli has endorsement deals with 17 brands. The brands Kohli previously endorsed include 3C Company, Celkon Mobiles, Cinthol (from Godrej), Clear (from Unilever), Fair & Lovely, Fastrack (from Titan), Pepsi, Flying Machine, Mattel, Munch (from Nestle), Oakley, Red Chief Shoes, Royal Challenge (from United Breweries), Sangam Suitings and Toyota Motors.

Was there anyone else?
