He joined the United States Foreign Service in 1929 and served in postings in Canada, Latvia, Poland and Lithuania during the years before and during World War II[5] and was US chief of mission in Berlin, East Germany, during 1955–58.[6] He was US consul in Colombo, Ceylon, c. 1951 to 1953.[7]
He was US ambassador to Ceylon (now Sri Lanka) from 1959 to 1961 and ambassador to Finland from 1961 to 1963.[8] He retired from service in 1968 and died of a sudden heart attack, while visiting Bonn, Germany, on 6 September 1973.[9]
Gufler's role as a diplomat acting in the U.S. interests, at many levels, cannot be underestimated. In the later years of World War II and early Cold War, he was instrumental in recommending that ex-Nazi POW generals and senior military officers be 'won over' to serve American (and Allied) intelligence interests in Europe, especially East Germany.[10] President John F. Kennedy used Gufler to deliver to Finnish president Urho Kekkonen a secret message during the Note Crisis.[11] During the peak of the Cold War in Berlin, he is remembered by other senior diplomats as the 'de facto ambassador' , in fact running the United States mission effectively, in 'counterpoise' to Soviet actions and intentions.[12][13] About his role in South Asia[14] a Pakistani senior diplomat commented that his services were 'invaluable' in promoting the United States' positive image and winning people 'towards realizing the Cold War imperatives' as espoused by the Americans.[15]
^Correspondence between Bernard A Gufler and Begum Mahmooda Salim Khan, September 1962; in the Begum Mahmooda Salim Khan (BMSK) Collection of papers/documents at the National Archives of Pakistan, Islamabad. Ambassador Gufler had been a close friend of the Begum's late husband, HE Ambassador Abdus Salim Khan, a senior Pakistani diplomat, and wrote an update of his various postings and transfers etc., to the Begum in 1962
^Kempton Jenkins, Cold War Saga pub Michigan: Nimble Books LLC, 2010, p 105. Kempton, himself a senior Cold War diplomat, served under Gufler and also remembers him as an 'expert' on Eastern Europe and Russia/the Soviet Union
^Hope M. Harrison, in Driving the Soviets up the Wall: Soviet-East German Relations, 1953-1961 (pub Princeton, NJ:Princeton UP, 2013) also mentions Gufler as a key person in the U.S. mission in Berlin at the time of the start of 'Berlin crisis' of 1958, see p 120 et aa. He was in fact later removed from his post in 1958 for espousing an overly-strong anti-Soviet response

Husain mentions Gufler by name, and makes much of his promoting a positive US image among people in the non-aligned Ceylon/Sri Lanka, and in also covertly promoting US relations with Pakistan, via his connections to senior Pakistani diplomats such as HE Mr Salim Khan, aa, and others. Husain also claims that Gufler and Salim Khan played a special role in convincing the Pakistani military commander-in-chief and later dictator, General Ayub Khan to visit the USA and to eventually develop a strong pro-USA and anti-Soviet policy in Pakistan.
