[1] In 1891, as a 5th year student, Alexandre Ramos was the first to diagnose a case of paroxysmal hemoglobinuria in Portugal, a rare form of Autoimmune hemolytic anemia, which he later studied as part of his licentiate thesis (oriented by Professor José Curry da Câmara Cabral, that was published in 1895).

During an outbreak of the infectious bubonic plague (spreading from house-to-house on the island), he worked with colleague António Joaquim de Sousa Júnior to treat patients and discovered solutions to reduce the propagation of the infection.

[1] At 35 years of age, Alexandre Ramos entered the political arena, leading the Partido Regenerador in Praia da Vitória, and then island-wide, where he obtained several electoral majorities.

[1] For his work, he was made Knight in the Order of St. James of the Sword (on 22 July 1901), and appointed sub-legate for health in Praia da Vitória, where he continued to serve the community in a modest, humble clinic.
