Biography
Henri Alexandre de Catt was born on June 25, 1725, in Morges, in the canton of Vaud, Switzerland, which was then under Bernese rule. Educated in the Swiss Reformed tradition and trained as a scholar, de Catt had a strong command of French, the main language for European intellectual life and diplomacy in the eighteenth century. His scholarly and language skills caught the eye of one of Europe's most powerful monarchs.
In 1758, during the challenging years of the Seven Years' War, de Catt began working for Frederick II of Prussia, known as Frederick the Great. Though informally called a Vorleser, or reader, his role was more complex. Frederick, who used French for his personal and literary correspondence and viewed himself as a French poet and philosopher, engaged de Catt to help improve his French pronunciation and writing. Thus, de Catt served as a private secretary, literary advisor, and trusted intellectual companion, not just a reader.
The bond between de Catt and Frederick was unusually close for a royal court. Frederick, known for his guarded and often scornful demeanor, seemed to find in de Catt a confidant with whom he could openly discuss everything from literature and philosophy to war strategies and personal doubts. De Catt was close to Frederick during the most critical moments of the Seven Years' War, providing him a unique inside view of the king's character.
Throughout his time at the Prussian court, de Catt kept a detailed diary of his talks with Frederick, views on court life, and reflections on the king's thoughts and moods. This diary wasn’t published during de Catt's life and remained in manuscript form for nearly a century. When it was finally published in 1885, it was recognized as a valuable historical document, offering insight into Frederick's spoken thoughts, literary views, and emotions unmatched by any other source.
De Catt spent the rest of his life connected to Prussia and its court culture, with his career built entirely around his role with Frederick. He died on November 23, 1795, in Potsdam, the Prussian royal residence where he spent many important years. Though he didn't produce major independent scholarly works, his diary ensured his lasting place in the history of eighteenth-century Prussia, especially regarding Frederick the Great.
Before Fame
Henri Alexandre de Catt was born and grew up in Morges, a small town by Lake Geneva in the Vaud region of Switzerland. This area was known for its Reformed Protestant culture and its closeness to the intellectual hubs of Geneva and Lausanne. French was the main language for educated discussions here. De Catt experienced a culture that appreciated classical studies and elegant French expression, and he followed an education grounded in Swiss Reformed humanism.
During the mid-eighteenth century, Europe was buzzing with intellectual activity, as the French Enlightenment was in full swing. Royal courts, from Saint Petersburg to Berlin, were eager to attract philosophers, scientists, and writers. Frederick the Great was known as a philosopher-king and wrote to Voltaire and other top thinkers of the time. In this environment, a Swiss scholar with excellent French and strong academic qualifications could find a place at one of Europe's most ambitious royal courts.
