[4] Georges Garnier was born in the 6th arrondissement of Paris on 14 May 1878, as the son of a baker, and together with the Huteau brothers and Fernand Canelle, he was a member of the small group of middle school students from the Lycée Chaptal who, in 1893, founded an unofficial club called the Etoile Sportive Parisiennne, which played on the pitch at the Château de Madrid in the Bois de Boulogne, and which was soon absorbed by Club Français, so called because it did not include any English players.

[10] On 29 April 1900, Garnier sustained an injury during the 1900 Challenge International du Nord final against Le Havre AC, so he changed to the position of goalkeeper, conceding a goal in extra-time in a 2–3 loss.

[11] He thus missed the final of the 1900 USFSA Football Championship on 6 May, which ended in another loss to Le Havre AC (0–1), partly because Club Français' "forward line was disorganized due to the absence of Garnier".

[4] In early 1902, Garnier intended to settle permanently in Bordeaux, playing a few games for the Stade Bordelais UC, but he ultimately decided to return to Paris.

[4] Outside of football, he was a modest office worker, becoming a fabric salesman, and on 4 February 1902, Garnier and Peltier had to leave the field during a match in order to catch a train back to work.

[15] On 4 January 1903, Garnier started in the final of the 1902 Coupe Manier at Le Vésinet, scoring a hat-trick to help his side to a 7–0 win over Olympique Lillois.

[4] On 1 April 1907, the 29-year-old Garnier started a match for the so-called Vieilles Gloires ("Old Glories"), playing alongside several fellow former Club Français players, including two of its founders, Charles Bernat and Ernest Weber; they lost 4–1 to Old Etonians.

[20] He was selected for both matches, which ended in a 0–4 loss to Upton Park on 20 September, and in a 6–2 victory over Belgium, which was mostly made up of students from the French-speaking Université libre de Bruxelles.
