18 July 1919: Élise Léontine Deroche was at Le Crotoy in northern France, co-piloting an experimental airplane, a civil variant of the Caudron G.3. The aircraft suddenly pitched down and crashed, killing Deroche and the pilot, M. Barrault. Mme Deroche was 36 years old.
According to a notice in Flight, “What happened is not very clear, but it would seem that the machine in which she was flying overturned during a trial flight. Baroness de la Roche was killed instantly and the pilot, Barrault, died very shortly afterwards.”
Élisa Léontine Deroche was born 22 August 1882 at nº 61, Rue de la Verrerie, in the 4earrondissement, Paris, France. She was the daughter of Charles François Deroche, a plumber, and Christine Calydon Gaillard Deroche. In her early life she had hoped to be a singer, dancer and actress. Mlle. Deroche used the stage name, “Raymonde de Laroche.”
Mlle. Deroche married M. Louis Léopold Thadome in Paris, 4 August 1900. They divorced 28 June 1909.
She had a romantic relationship with sculptor Ferdinand Léon Delagrange, who was also one of the earliest aviators, and it was he who inspired her to become a pilot herself. They had a son, André, born in 1909. Delagrange was killed in an airplane accident in 1910. They never married.
After four months of training at Chalons, under M. Chateu,¹ an instructor for Voison, Mme Deroche made her first solo flight on Friday, 22 October 1909. On 8 March 1910, Élisa Léontine Deroche was the first woman to become a licensed pilot when she was issued Pilot License No. 36 by the Aéro-Club de France.
In a 30 October 1909 article about her solo flight, Flight & The Aircraft Engineer referred to Mme. Deroche as “Baroness de la Roche.” This erroneous title of nobility stayed with her in the public consciousness. Deroche participated in various air meets, and on 25 November 1913, made a non-stop, long-distance flight of four hours duration, for which she was awarded the Coupe Femina by the French magazine, Femina.
On 20 February 1915, Mme. Deroche married Jacques Vial at Meudon, Hauts de Seine, Île-de-France, France.
During World War I she was not allowed to fly so she served as a military driver.
Many sources report that Mme Deroche set two altitude records at Issy-les Moulineaux in June 1919, just weeks before her death. One, for example, is said to have been 5,150 meters (16,896 feet), 12 June 1919. The Fédération Aéronautique Internationale (FAI), however, did not recognize records set by women until 28 June 1929.
Élisa Léontine Deroche was buried at the Cimetière du Père-Lachaise, Paris, France.

1 April 1921: Adrienne Bolland, a pilot employed by René Caudron to demonstrate his airplanes in South America, flew a Caudron G.3 from Mendoza, Argentina to Santiago, Chile, across the Andes Mountain Range.
Mlle Bolland’s route followed the Paso de Upsallata, passing south of Aconcagua, at 6,960.8 meters (22,837 feet), the highest mountain in the Andes, and north of Volcan Tupangato, 6,570 meters (21,580 feet). The duration of the flight was 4 hours, 17 minutes.
Bolland was awarded a gold medal by the Argentine League of Patriots at Buenos Aires.
Mdlle. Bolland Crosses the Andes
From a Daily Mail report Mdlle. Bolland, the French aviatress, on April 1, left Mendoza, Argentina, at 7.30, and flew over the Andes Mountains, arriving at Santiago in Chile, just three hours later.
This the second time Mdlle. Bolland has flown over the Andes.
The distance Mdlle. Bolland covered was about 112 miles. There are heights of more than 20,000 ft. in the neighborhood of the point at which she crossed the range.
We are just wondering whether the journey was a “non-stop” one, with strong headwinds, or whether a halt was made en route, and if the latter, where.

Adrienne Armande Pauline Boland was born at Arcueil, a suburb of Paris, France, 25 November 1895. She was the youngest of seven children of writer Henri André Joseph Boland and Marie Amélie Elisabeth Françoise Allonie (Marie Joséphine) Pasques. Her father died in 1909, and her mother sometime later.
At the age of 24, she decided to learn to fly and enrolled in flight training at Société des Avions Caudron (the Caudron Airplane Company), Le Crotoy. She started training 16 November 1919 and was awarded her pilot’s license 29 January 1920. An error on the certificate spelled her surname with two “l”s, and she retained the name “Bolland” for the rest of her life.
Mlle Bolland was employed by René Caudron to transport airplanes to and from the factory. She told Caudron that she wanted her own airplane. He told her that if she could perform a loop in a Caudron G.3, a pre-World War I scout plane, that she could fly it for the company. She did, and was then asked to fly it across the English Channel, which she did, 25 August 1920.
Caudron sent her to Argentina to demonstrate his airplanes. Once there, she planned to fly across the Cordillera de los Andes (the Andes Mountain Range) to Chile on the western coast of South America. The mountains were higher than the airplane was capable of flying, so she had to fly through valleys to find a way across. Departing Mendoza, Argentina at 6:00 a.m, she headed across the 400-kilometer (250 miles) wide mountain range. Most of the flight was at an altitude of 4,500 meters (14,764 feet) and it was extremely cold. Without maps, she succeeded: “Suddenly I saw a break in the mountains. . . and in the distance, the plain of Chile. I was saved.”
The airplane was sold in Santiago and Bolland returned to Buenos Aires by train.
After returning to France, Mlle Bolland was a frequent participant at air meets, displaying her skills in aerobatics. She flew two Caudron C.27s, G-AGAP (c/n 5533.7) and F-AGAQ (c/n 5534.8), both registered in her name 27 February 1924. At the Aérodrome d’Orly, Paris, on 27 May 1924, she took off at 4:12 p.m., completed 212 consecutive loops, then landed at 5:25 p.m. (The Caudron C.27 was redesignated C.127 in late 1924.)
In 1924, France named Adrienne Bolland Chevalier de la légion d’honneur for her flight across the Andes.
Ernest Jean Baptiste Charles Vinchon married Mlle Bolland in Paris, 15 March 1930.
After the surrender of France to Nazi Germany in 1940, M. and Mme Vichon remained in occupied France and became agents of the Confrérie Notre-Dame (CND, or Brotherhood of Notre Dame, later called CND-Castile), an intelligence organization of the Forces françaises libres (Free French Forces).
For her services during World War II, in 1947 Mme Vichon was advanced to the rank of Officier de la Légion d’honneur.
Adrienne Bolland Vichon died at Paris, France, 18 March 1975 at the age of 79 years. She was buried in Donnery, Loiret.
Adrienne Bolland crossed the Andes in a Caudron G.3, c/n 4902, registered F-ABEW. The Caudron G.3 was a World War I reconnaissance airplane and flight trainer manufactured by Société des Avions Caudron. It is called a sesquiplane because the lower wing is significantly shorter than the upper. The G.3 was a single-engine aircraft that was built in single- and two-place variants. The engine and cockpit are contained in a very short fuselage, supporting the wings and landing gear. Tail control surfaces are mounted on an open framework tail boom.
The Caudron G.3 was 6.40 meters (21 feet) long with an upper wingspan of 13.40 meters (44 feet). The height of the aircraft was 2.50 meters (11 feet, 2 inches). The airplane had an empty weight of 420 kilograms (926 pounds) and maximum weight of 710 kilograms (1,565 pounds).
The G.3 was powered by an air-cooled, normally-aspirated 10.910 liter (665.791 cubic inches) Société des Moteurs Le Rhône 9C nine cylinder rotary engine with a compression ratio of 5:1. It was rated at 70 cheval vapeur (1 ch = 0.99 horsepower) at 1,100 r.p.m., and 80 cheval vapeur at 1,200 r.p.m., but able to produce a maximum 92 cheval vapeur (90.77 horsepower) at 1,300 r.p.m. It drove a two-bladed, fixed-pitch wooden propeller. The 9C was 0.810 meters (2 feet, 7.9 inches) long, 0.930 meters (3 feet, 6.1 inches) in diameter and weighed 119 kilograms (262 pounds).
The Caudron G.3 had a maximum speed of 106 kilometers per hour (66 miles per hour) and service ceiling of 4,300 meters (14,108 feet).
