Abstract

Faz-se uma breve reconstru\c{c}\~ao hist\'orica de alguns pontos que, de algum modo, contribu\'iram para o trabalho seminal de Louis de Broglie. Em particular, enfatiza-se a relev\^ancia de sua tese de doutorado, principalmente por seu valor epistemol\'ogico, ao ampliar a crise que havia sido introduzida na descri\c{c}\~ao da radia\c{c}\~ao pelo \textit{quantum} de Planck, abrindo caminho para sua solu\c{c}\~ao. A brief historical reconstruction of some points that, in some way, contributed to Louis de Broglie's seminal work is made. In particular, the relevance of his doctoral thesis is emphasized, mainly for its epistemological value, in expanding the crisis that had been introduced in the description of radiation by Planck's quantum, paving the way for its solution.
