Google doodle celebrates Dr Mario Molina a nobel prize winner

 


Mario Molina was a Mexican chemist who was born on March 19, 1943, in Mexico City, Mexico, and died on October 7, 2020, in Mexico City, Mexico. He was best known for his research on the depletion of the ozone layer in the Earth's atmosphere and his work on the environmental effects of human activity.


Molina earned his bachelor's degree in chemical engineering from the National Autonomous University of Mexico (UNAM) and his Ph.D. in physical chemistry from the University of California, Berkeley. He worked at the Jet Propulsion Laboratory in Pasadena, California, before joining the faculty at the Massachusetts Institute of Technology (MIT) in 1989.


In 1974, Molina and his colleague, Sherwood Rowland, published a paper that outlined the potential danger of chlorofluorocarbons (CFCs) to the ozone layer. Their work led to the Montreal Protocol, an international treaty that has been successful in reducing the production of CFCs and other ozone-depleting substances.


Molina's contributions to science were recognized with numerous awards and honors, including the Nobel Prize in Chemistry in 1995, which he shared with Rowland and Paul Crutzen, for their work on atmospheric chemistry. He was also awarded the Presidential Medal of Freedom, the highest civilian honor in the United States, by President Barack Obama in 2013.



Molina was a prominent advocate for the role of science in public policy and worked to raise public awareness about environmental issues. He was also a mentor to many young scientists and was actively involved in promoting science education and outreach programs.


For their work, Molina and Rowland shared the 1995 Nobel Prize for Chemistry with Paul J. Crutzen of the Max Planck Institute in Germany. In announcing the award, the Royal Swedish Academy of Sciences said the researchers "have contributed to our salvation from a global environmental problem that could have catastrophic consequences."

In 2013, President Barack Obama awarded Molina the Presidential Medal of Freedom, the highest civilian honor in the US.

Molina died of a heart attack in 2020 at the age of 77.
