Ernst Rudolf Jaakson (11 August 1905, Riga – 4 September 1998, New York) is recognized by the U.S. Department of State as the world’s longest-serving diplomat, having spent 79 years in Estonia’s Foreign Service. He is regarded as one of Estonia’s most respected diplomats, credited with preserving the legal continuity of the Estonian Republic during the Soviet occupation from 1940 to 1991.
Throughout those decades, Jaakson maintained close contact with senior U.S. officials and became a symbol of Estonia’s statehood in exile, tirelessly advocating for its independence. The U.S. policy of non-recognition of the Soviet occupation of Estonia was a key factor that enabled Ernst Jaakson’s decades-long diplomatic work and supported Estonia’s eventual restoration of independence in 1991. Following the restoration of independence in 1991, he was appointed Ambassador to the United States and Permanent Representative to the United Nations—at the age of 86. He later resumed his role as Consul General in New York until his death.
Jaakson is remembered as a dignified and principled statesman whose unwavering dedication helped sustain Estonia’s international legal status and inspired belief in its eventual freedom.
Early Life and Roots
Ernst Jaakson was born on August 11, 1905, in Riga—then part of the Russian Empire, now the capital of Latvia — to ethnically Estonian parents with ancestral roots on the island of Hiiumaa in Estonia.

He grew up in a culturally vibrant Baltic region where Estonian communities maintained a strong sense of national identity despite foreign rule.
After Estonia declared its independence in 1918, Jaakson moved to the newly established republic, where he would later begin his lifelong diplomatic career.
Joining the Foreign Service
Ernst Jaakson began his diplomatic career remarkably early, joining the Estonian Embassy in Riga as a referent on August 20, 1919, at just 14 years old. This early entry into foreign service coincided with the formative years of the newly independent Republic of Estonia, which had declared its independence the previous year and was actively establishing its diplomatic presence abroad.
After completing his mandatory military service in the Estonian Defence Forces, Jaakson resumed his diplomatic career. In 1928, he formally joined the Estonian Ministry of Foreign Affairs as a trained official. That same year, he was assigned to the Estonian Consulate General in New York, where he would spend most of his career and play a key role in maintaining Estonia’s diplomatic continuity throughout the Soviet occupation.
It is worth noting that, due to the turmoil of the 20th century, Jaakson was able to visit Estonia again only in 1992, after the country had regained its independence following the end of Soviet occupation.

Service in San Francisco
From 1929 to 1932, Ernst Jaakson served as secretary at the Estonian Honorary Consulate in San Francisco, working under Honorary Consul Martin Coffer. This posting came at a time when Estonia was actively building its diplomatic and consular network to support trade, diaspora communities, and political recognition abroad. Jaakson’s duties included assisting Estonian nationals on the West Coast, managing official correspondence, and helping strengthen Estonia’s international presence during the interwar period—a crucial time for the young republic.

From 1932 to 1940, Ernst Jaakson served at the Estonian Consulate General in New York. Despite Estonia losing its independence in 1940 following the illegal Soviet occupation, Jaakson steadfastly continued to represent the Republic of Estonia in exile. Through his dedication, he upheld Estonia’s legal continuity and sovereignty on American soil throughout the decades of occupation.
Welles Declaration
On 23 July 1940, Acting U.S. Secretary of State Sumner Welles issued what later became known as the Welles Declaration—a pivotal statement rejecting the forcible annexation of Estonia, Latvia, and Lithuania by the Soviet Union. The declaration, grounded in the principle of non-recognition of territorial changes achieved by force, affirmed that the United States would not recognize the legitimacy of the Soviet occupation of the Baltic States. This non-recognition policy provided essential legal and diplomatic grounds for the continued operation of the Baltic foreign services in exile. For Estonia, it allowed diplomats like Ernst Jaakson to maintain official representation abroad, preserve legal continuity, issue passports and documents, and advocate for national independence—all with the tacit support of the U.S. government and its allies.

Visiting Estonian refugees

In October 1946, Ernst Jaakson visited Estonian refugees aboard the ship Linda docked at the Port of Miami. These refugees were among the many displaced by the turmoil of World War II and the subsequent Soviet occupation of Estonia.
Jaakson’s visit demonstrated his unwavering commitment to the Estonian diaspora, offering support and reassurance to those uprooted from their homeland. Through such efforts, he helped maintain a sense of community and national identity among Estonians abroad during a time of great uncertainty and hardship.
Continued Service in New York

Ernst Jaakson continued his diplomatic service in New York throughout the decades of Soviet occupation. Initially serving as consul, he was appointed consul general and chargé d’affaires in 1965, following the death of Johannes Kaiv. Operating under the principle of legal continuity, Jaakson became one of the very few diplomats in the world to represent a nation under foreign occupation, maintaining Estonia’s official presence and voice in the international community. His unwavering commitment ensured that Estonia’s independence was never forgotten or deemed lost by its allies.
The Estonian consulate in New York was able to continue operating financially thanks to the U.S. government’s 1941 decision to allow the use of Estonia’s frozen assets held in American banks.
Keeping up contacts with senior U.S. officials
Jaakson regularly met with senior U.S. officials to advocate for Estonia’s independence. Notable meetings include meetings with President Lyndon B. Johnson in 1967, with President Richard Nixon in 1971, with President Gerald Ford in 1976, President Jimmy Carter in 1977, President Ronald Reagan in 1985.

On 23 June 1969, Ernst Jaakson, Estonia’s Consul General in New York, received a letter from NASA asking him to ask for a goodwill message from his country’s leaders that US astronauts could take to the Moon with them. Since Estonia was then deep into the Soviet occupation period while the Republic of Estonia lived on in people’s memories and hearts, Ernst Jaakson, one of the few remaining official representatives of the Republic of Estonia, wrote the message himself. He sent the message off so that it would reach NASA by 30 June 1969 at the latest to be transmitted to microfilm on time.
On 21 July 1969, history was made and the first person stepped on the surface of the Moon. The Apollo 11 crew carried with them the message from the Republic of Estonia, together with goodwill messages from 73 other countries. These are engraved on a tiny disc made of silicon together with statements from four US presidents.

Ernst Jaakson’s message on behalf of the Republic of Estonia was succinct and hopeful:
“The people of Estonia join those who hope and work for freedom and a better world.”
Supporting Estonians Abroad

Ernst Jaakson played a pivotal role in initiating and supporting projects that fostered Estonian identity and community abroad.
One of the most significant of these was the creation of ESTO (Estonian World Festival), which brought together Estonians from around the globe to celebrate their culture and heritage.
The inaugural ESTO festival was held in 1972 in Toronto, Canada, marking a landmark event in uniting the Estonian diaspora.
After Estonia regained its independence
In 1991, following Estonia’s restoration of independence, Jaakson was appointed Ambassador to the United States and Permanent Representative to the United Nations. He presented his credentials to President George H. W. Bush in November 1991.
