[7][8][4][9] When World War II broke out, Suger's father was called up to complete his mandatory military service.

[10] Suger's mother spoke no German despite living in Switzerland and traveled to the Guatemalan Consulate in Germany for help returning to Guatemala.

[10][4][3][15] While at UTA, he was inducted into Sigma Xi science society;[4][6] did labwork in a molecular physics group; and was an academic assistant for a postgraduate Classical Mechanics course.

[13][6] During the Guatemalan Civil War, he was approached by Chief of Defense Staff General Marco Antonio Espinoza to engineer a computerized system that would help the government monitor revolutionaries and other dissidents.

[23] They claimed that Suger's technological modernization within the military and his tracking system worsened the human rights violations that characterized the war.

[23] This sentiment echoes Albedrío magazine, the Pro-Human Rights Action Foundation, and Rafael Landívar University's student newspaper Plaza Pública, who directly suggest he should be held accountable for his indirect influence on the violence.

[15][22][24][25] Many publications, such as InSight Crime and El Observador GT, as well as academics like Jennifer Schirmer (Historical Clarification Commission) and Hal Brands (Johns Hopkins), merely refer to the intelligence systems he helped develop rather than directly by name.

[15] He planned to eliminate poverty by expanding the middle class and by heavily investing in and empowering those in the war-torn northwestern part of the country.

[14][36] In 1960, Suger met Regina Margarita Castillo Rodríguez during a visit to Guatemala while on holiday from ETH Zürich.

[8] The couple has five sons: José Eduardo, Carlos Enrique, Emilio Alejandro, Christian Andree, and Jean Paul.

[6] Suger published four editions (1971, 1974, 1978, 1981) of the textbook Introducción a la matemática moderna, which he wrote with Bernardo Morales Figueroa and Leonel Pinot Leiva.
