Combien pesait Robert Wadlow quand il est mort ?
Robert Pershing Wadlow, also known as the Alton Giant and the Giant of Illinois, was an American man who was the tallest person in recorded history for whom there is irrefutable evidence. He was born and raised in Alton, Illinois, a small city near St. Louis, Missouri. Wadlow's height was 8 ft 11.1 in (2.72 m) while his weight reached 439 lb (199 kg) at his death at age 22. His great size and his continued growth in adulthood were due to hypertrophy of his pituitary gland, which results in an abnormally high level of human growth hormone (HGH).

La taille de Wadlow atteignait 2,72 m (8 pi 11,1 pouces) et son poids a atteint 199 kg (439 livres) au moment de sa mort, à l'âge de 22 ans. Sa grande taille et sa croissance continue à l'âge adulte étaient dues à une hypertrophie de son hypophyse, qui entraîne un taux anormalement élevé d'hormone de croissance humaine (HGH).

### Draft ###

### 1. Query Parsing

"Combien pesait Robert Wadlow quand il est mort ?" 

→ "How much did Robert Wadlow weigh when he died?"

Simple information retrieval. Weight at death. ● High confidence domain.

### 2. Subject Identification  

Robert Wadlow. The Alton Giant. ● Confirmed: tallest verified person in recorded history.

Born: 1918, Alton, Illinois. Died: 1940, St. Louis. Age 22.

Key metrics from memory:
- Height: 8'11.1" (2.72m) ●
- Weight: ~439 lbs (199kg) ●

### 3. Weight Data Verification

439 pounds. 199 kilograms. ≈ 31 stone.

Cross-reference against known physiological constraints:
- Human growth hormone (pituitary gland) → extreme height/weight
- Frame size vs. muscle mass distribution
- Cardiovascular stress at that scale

Physically plausible? ● Yes. Growth patterns consistent.

### 4. Medical Context

Pituitary gland hypertrophy → excessive HGH production. 

∴ Both height and weight extreme, but weight-to-height ratio not obviously unhealthy for his condition.

⚠ Note: Would be extremely obese for normal-height person, but proportional for 8'11" frame.

### 5. Information Synthesis

Death factors: leg brace failure, infection, blood clots. July 1940.

Weight at death: 439 lbs (199kg). ● High confidence.

Physical condition: weakened by circulatory issues, but weight within expected range for his height and hormonal condition.

### 6. Answer Construction

Direct response: 439 livres (199kg). Age 22. Context of pituitary disorder.

French response structure:
- Direct answer first
- Metric system (kg preferred in France)  
- Brief medical context
- Age/location details
- Height reference for scale

☑ Information retrieval complete
☑ Physical plausibility verified  
☑ Cross-cultural presentation adapted

### Answer###
Robert Wadlow pesait 439 livres (199 kilogrammes) au moment de sa mort. Il était âgé de 22 ans à ce moment-là. Cette taille considérable et ce poids élevé résultaient d'une hypertrophie de sa glande pituitaire, qui entraînait un taux anormalement élevé d'hormone de croissance humaine.
