Luis Ernesto Miramontes Cárdenas (March 16, 1925 – September 13, 2004) was a Mexican chemist known as co-inventor and the first to synthesize an oral contraceptive, progestinnorethisterone.
On October 15, 1951, under the supervision of Carl Djerassi and the direction of George Rosenkranz at Syntex laboratory in Mexico City, Miramontes completed the first ever synthesis of an oral contraceptive: progestin norethisterone.
While Djerassi is sometimes regarded as 'Father of the Pill'".,[1] it was Miramontes, working under Djerassi's supervision, that achieved the first synthesis. In the words of Djerassi, "On 15 October 1951, Luis Miramontes, a young Mexican chemist doing his undergraduate bachelor's thesis work at Syntex completed the synthesis of the 19-nor-17α-ethynyltestosterone or, for short 'norethisterone'—which turned out to be the first oral contraceptive to be synthesized.".[2] Nobel Laureate Max Perutz added "the chemistry student Luis Miramontes, working under the direction of Djerassi and the director of the laboratory Jorge Rosenkranz synthesized the compound".[3] The last step of the synthesis method was registered on page 114 of the Miramontes's personal laboratory notebook (signed).
All three Miramontes, Djerassi, and Rosenkranz are listed on the patent as co-inventors.
Patent of the first oral contraceptive, elected to the USA Inventors Hall of Fame.
In 1964, the contraceptive pill was chosen by the US Department of Patents as one of the 40 registered more important inventions between 1794 and 1964. The name of Luis Miramontes appeared next to Pasteur, Edison, Bell, the Wright brothers and others of equal stature. It was included in the "USA Inventors Hall of Fame".[4]
In 1985 he received the "Estado de Mexico" Medal, in the area of sciences and arts;[5] as well as a public recognition from the government of the state of Nayarit, and an academic recognition from the Technological Institute of Tepic.
He received the Mexican National Prize on Chemistry "Andrés Manuel del Rio" in 1986.
In 1989 he became a "pugwashite", that is, member of the Pugwash Conferences on Science and World Affairs, organization promoting peace and world development, after attending the 39th Pugwash Conference: Building Global Security through Cooperation held at Cambridge, USA.[6] The Pugwash Conferences were awarded the Peace Nobel Prize in 1995.
In 1992 the General Hospital of Zone no. 1, of the Mexican Institute of Social Security, in Tepic, Nayarit, was named "Luis Ernesto Miramontes Cardenas Hospital".[7]
In 1994 the Mexican Ministry of Health recognized his scientific contributions, when installing the National Program on Family Planning in Mexico.
He received in 1998, on behalf of the government of the state of Nayarit, the "Amado Nervo" Medal.

In 2000, the contraceptive pill was denominated three times as one of the most important inventions of the last 2000 years, by a group of outstanding persons, that included several Nobel laurates.[8]
In 2001, at the 50th Anniversary of the synthesis of norethisterone, the UNAM and the Mexican Ministry of Health, organized individual tributes to Miramontes and Rosencraz.
In 2003, norethisterone was considered one of the most important 17 molecules that have influenced the history of humankind.[1]
In 2004, the invention of Luis E. Miramontes was chosen as the twentieth most important one of all the times. The election was organized by SCENTA, an initiative of The Engineering and Technology Board of the United Kingdom.
In 2005, the Mexican Academy of Sciences, named the invention of Miramontes as the Mexican most important contribution to world science ever.[9]
In 2009, the BBC of London nominated him as one of the five most important Latin American researchers of all the times[10]
In 2009, The School of Chemistry of UNAM recognized him as one of the most successful and important scientists to have received a degree from it[11]
In 2009, The School of Chemistry of UNAM honored him by naming the 2009 year prize QUIMIUNAM after him.[12]
In 2010, TCE Today, published by the IChemE regarded him "one of the chemical engineers who changed the world" [13]
In 2010, The Innovators of America initiative nominated him a top Icon & Legend of America[14]
In 2011 was named one of the world’s most influential chemical engineers of all time by the IChemE (Institution of Chemical Engineers).[15]
In 2011, The Mexican Institute of Chemical Engineers IMIQ named after him the Prize "Ing. Luis Ernesto Miramontes Cárdenas" aimed to recognize outstanding Mexicans in Chemical Engineering R&D .[16]
