1901 Cuban Government Authentication Certificate Signed by Dr. Diego Tamayo, Certifying that John Hay is US Secretary of State

On offer is a remarkable Cuban governmental certificate dated December 15, 1901, signed by Dr. Diego Tamayo (1853-1926), then Secretario de Estado y Gobernación (Secretary of State and Government) in Cuba. The document authenticates the position and signature of John Hay, Secretary of State of the United States, whose name appears on what was once an attached U.S. document [the formerly attached document is not present]. This was part of the legalization process through which the transitional Cuban government verified foreign diplomatic papers before the island’s formal independence in 1902. The document reads in part: “The undersigned Secretary of State and Government certifies that John Hay, whose authentic signature appears at the foot of the attached document, is, and was at the date when he signed it, Secretary of State of the United States of America. In witness whereof, I authorize this certificate with my signature and order it sealed with that of this Secretariat. Havana, December 15, 1901.” The document is numbered 4275, stamped “GRATIS”, and displays an embossed seal of the Secretariat together with Tamayo’s bold manuscript signature. This document represents the earliest phase of Cuban self-governance under U.S. occupation. The Secretaría de Estado y Gobernación, established during the military government of General Leonard Wood, functioned as Cuba’s first national ministry. Dr. Diego Tamayo, a delegate to the 1901 Constitutional Convention and one of the island’s earliest civilian administrators, is often regarded as the de facto first Secretary of State of Cuba [SEE BIO NOTES AT THE END OF THE LISTING FOR MORE ON DR. TAMAYO]. His role was central in shaping the bureaucratic framework that carried into the First Republic after independence in 1902. Tamayo’s signature marks this document as an artifact of the birth of Cuban diplomacy. Issued months before the Republic’s inauguration, it evidences the continuity of Cuban civil authority during the occupation and its participation in international legal affairs. The act of certifying John Hay’s signature—linking two architects of early 20th-century hemispheric policy—symbolizes the complex interdependence of Cuba’s emerging sovereignty and U.S. oversight. This document measures approximately 12.5x8 inches. It is overall G+. It shows signs of aging with light folds, even toning, and a fully legible autograph of Tamayo. The watermark corresponds with typical Cuban government documents of the time. BIO NOTES: Dr. Diego Tamayo Figueredo (1852–1926) born in Bayamo and trained as a physician in Spain. He was a pioneering Cuban physician and statesman. He was known as the “father of Cuban microbiology” and was the country’s first effective Secretary of State and Government during the U.S. military occupation. In his medical career, Dr. Tayamo worked with Carlos J. Finlay on anti–yellow fever campaigns and was the founder of Cuba’s first bacteriological laboratories and vaccination institutes. As head of the Secretaría de Estado y Gobernación, Dr. Tamayo oversaw the organization of Cuba’s first national ministries and helped implement the administrative framework that would carry into the First Republic. A delegate to the 1901 Constitutional Convention and later a senator, Tamayo’s political and scientific careers together mark him as a central figure in shaping both the government and the public health foundations of modern Cuba.
