Stig Synnergren

General Stig Gustaf Eugén Synnergren (25 February 1915 – 29 April 2004) was a senior Swedish Army officer. Synnergren had an illustrious military career that began in 1939 as a second lieutenant. He played a pivotal role during World War II, serving in the Ski Battalion and conducting intelligence operations in Northern Norway after the German occupation of Narvik. His exceptional skills and experience led him to manage the evacuation of Norwegian refugees in Jokkmokk.

Synnergren's rapid ascent through the ranks continued, including graduation from the Royal Swedish Army Staff College and various military studies abroad. He held teaching positions and became a major while heading the Tactics Department. Notably, he became the Chief of the Army Staff in 1963 and ultimately achieved the rank of Supreme Commander of the Swedish Armed Forces in 1967. During his tenure as Supreme Commander, Synnergren oversaw significant defense policy changes, including the abandonment of neutrality and the development of the Saab 37 Viggen aircraft. He also led reorganization efforts and cutbacks in the Army and Navy.

Synnergren was widely associated with military intelligence, particularly during the exposure of the secret intelligence agency IB. Beyond his military career, Synnergren held various positions of trust in organizations such as the Swedish Tourist Association, Swedish Ski Association, and corporate boards. He also served on the board of the East Economic Office, a unique agency within Swedish military intelligence. Synnergren was famous for advancing from the rank of captain to becoming the "youngest general in the modern times" in just five years.
