My constitutional law professor assigned his book on Mexico's constitutions my junior year and I still have my copy, full of underlines. I read half of it on a bus to Columbus with my abuela's old dictionary next to me, trying to get the legal Spanish right. Didn't know much about him beyond the page but that book shaped how I think about how countries write their own rules.

Fernando Serrano Migallón was a Mexican jurist, historian and university teacher, a son of the Spanish Republican exile who became one of the leading authorities on Mexican constitutional history and on copyright law. A professor emeritus of the National Autonomous University of Mexico (UNAM), twice its general counsel and for eight years director of its Faculty of Law, he was also a member of the Mexican Academy of Language. He died on 27 October 2026, aged 81.
He was born in Mexico City on 26 June 1945, the youngest of six children and the only one born in Mexico. His father, Francisco Serrano Pacheco, had been a lawyer and one of the last public prosecutors of the Second Spanish Republic, and reached Mexico in 1942; the rest of the family followed in 1944. Serrano Migallón studied law and economics at UNAM, took a certificate at the International Institute of Public Administration in Paris and a diploma from The Hague Academy of International Law, and later earned a doctorate in history at UNAM.
He taught political science, theory of the state, international law and constitutional law at UNAM's Faculty of Law, and also taught at El Colegio de Mexico. He served UNAM as general counsel in 1993 to 1995 and again in 2000, then directed the Faculty of Law from 2000 to 2008, renewing its curricula. In public life he held legal posts in several federal ministries, helped draft the Federal Copyright Law, took part in the reorganisation that created the National Copyright Institute and later directed it. He was secretary general of the Chamber of Deputies, cultural and artistic secretary of Conaculta from 2009 to 2011, under secretary for higher education from 2012 to 2014 and director of the Instituto Alfonso Reyes.
He wrote more than 50 books, among them the ten volume La vida constitucional de Mexico, Historia minima de las constituciones en Mexico, El asilo politico en Mexico and La inteligencia peregrina, a study of the Spanish Republican intellectuals who came to Mexico. He wrote for El Universal and Excelsior, joined the Mexican Academy of Language in 2006 and presided over the Mexican Academy of Jurisprudence and Legislation. He received the National Prize for Arts and Literature in 2021, French and Spanish orders of merit, and in February 2026 UNAM's University Council named him professor emeritus unanimously.
His death on 27 October 2026 was announced by his family, UNAM's Faculty of Law and the Mexican Academy of Language. No cause of death was made public. A wake was held that evening at the Panteon Frances de San Joaquin in Mexico City, followed by a funeral Mass and cremation the next day. UNAM recalled that he called teaching the thing he liked most in life.

How he described teaching, as recalled by UNAM after his death

That book is still used in classes here in Mexico too, it's a huge compliment that it traveled that far.
