The surname Grandjean is of French origin, derived from the Old French "grand" meaning 'great' or 'large', and "jean" which is a common medieval nickname for John or Jeanne, derived from the Hebrew name Yochanan, meaning 'God is gracious'. Thus, the name Grandjean can be interpreted as 'The Great John' or 'The Large John'. It was likely used to distinguish between multiple individuals with the given name John in a particular community. The surname became popular during the High Middle Ages, a period when the practice of using hereditary surnames began to spread in Europe. The Grandjean family name can be found across France and its territories, as well as other regions where French colonization or immigration occurred, such as Canada, the United States, and various Caribbean islands.
The last name Grandjean has its origins in France, particularly in the region of Normandy and Brittany, where it is most prevalent due to historical population clusters. Over time, the name has also spread to other parts of France as well as neighboring countries such as Belgium, Switzerland, and Canada (specifically Quebec), reflecting migration patterns during various periods in history. In North America, it can be found primarily in Quebec and its diaspora communities across Canada and the United States, especially in states with significant French-speaking populations like Louisiana and Maine. The name is less common but still present in countries where there are French expatriates or colonization influences, such as South America (Brazil, Argentina) and Africa (Reunion, Senegal, Algeria). In the English-speaking world, the distribution of Grandjean is relatively sparse compared to its French-speaking counterparts.
The surname Grandjean has several variants and spellings due to differences in transcription and translation over time and across regions. Some common variations include Grand Jean, Grangien, Grand-Gian, Grandgienne, and Granjien. Additionally, there might be regional or familial variations such as Grand'Jaen, Grandjehan, Grandjeann, Grandjeant, Grandjeannot, and Grandjeanneau. Furthermore, changes in the use of accents, hyphens, or lack thereof can also result in alterations to the name's spelling, such as Grand-Jean, Grand Jeanne, or Grandjeaun. These variations reflect the diversity of the Grandjean family and its history.

1. Charles-Édouard Jeanneret-Grandjean (1887-1965), known professionally as Le Corbusier, was a Swiss-French architect, designer, and painter who is one of the pioneers of modern architecture. His innovative designs, including the Villa Savoye, significantly impacted 20th-century architectural development.
2. Frédéric Grandjean (1948-), a French biochemist, is best known for his work on environmental toxicology and exposure assessment. He has authored numerous publications on pharmacokinetics and risk assessment of chemicals in the environment.
3. Émile Grandjean (1876-1934) was a Danish bacteriologist who made significant contributions to the understanding of infectious diseases, particularly dysentery and cholera. He is credited with identifying the presence of Vibrio cholerae in human feces, which played an important role in the prevention and control of cholera epidemics.
4. Michel Grandjean (1925-), a Swiss physician and epidemiologist, was a pioneer in the field of environmental health.

Over time, this surname has spread throughout France and other European countries due to migration and the formation of new families. In North America, the Grandjean family is particularly prominent in Quebec, Canada, where many descendants can be traced back to the first immigrants who arrived in the 17th century. Variations of the name include Grandjan, Grandgian, Grangien, and other regional spellings.
