The Historic Decision00:01:58

In March 1938, President Lázaro Cárdenas decreed the expropriation of foreign oil companies, a decision supported by the Mexican people and the university community through massive demonstrations.

Technical Challenges and Innovation00:06:34

Faced with the exodus of foreign technicians and a boycott on equipment and parts, Mexican engineers and workers improvised repairs and manufactured their own components to keep refineries operational.

The Tetraethyl Lead Challenge00:14:17

Transnational companies attempted to cripple Mexico by withholding tetraethyl lead for gasoline production. Mexican scientists successfully developed the substance domestically despite dangerous working conditions, eventually forcing the companies to abandon their boycott.

Legacy and Scientific Growth00:18:12

The success of the nationalized oil industry served as a catalyst for scientific research and the development of new academic programs, fostering greater technological independence for Mexico.

Context of the Expropriation00:00:24

In 1937, shortly before the expropriation, Mexico had very few trained chemical engineers capable of managing the oil industry, which was then controlled by foreign interests.
