Question: What French man did technical drawings of a buildings?

full_context: Document 1: Drafter: A drafter, draughtsman (British English) or draftsman, drafting technician (American English and Canadian English) is a person who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts.
Document 2: First Architect to the King: Under the Ancien Régime, the First Architect to the King (French: "Premier Architecte du Roi" ) was the direct assistant to the general director of the building industries, arts and manufactures of France and, consequently, number 2 of the Bâtiments du Roi, forming part of the Secretary of State of the Maison du Roi.
Document 3: Charles-Louis Balzac: Charles-Louis Balzac (1752 – 1820) was a French architect and architectural draughtsman.
Document 4: Technical pen: A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. "Rapidograph" is a trademarked name for one type of technical pen. Technical pens use either a refillable ink reservoir (Isograph version) or a replaceable ink cartridge.
Document 5: Architectural drawing: An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture. Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to enable a building contractor to construct it, as a record of the completed work, and to make a record of a building that already exists.
Document 6: Charles Cameron (architect): Charles Cameron (1745 – 19 March 1812) was a Scottish architect who made an illustrious career at the court of Catherine II of Russia. Cameron, practitioner of early neoclassical architecture, was the chief architect of Tsarskoye Selo and Pavlovsk palaces and the adjacent new town of Sophia from his arrival in Russia in 1779 to Catherine's death in 1796. All his indisputable tangible works "can be encompassed in a day's tour"; Cameron concentrated exclusively on country palaces and landscape gardens. Twice dismissed by Paul of Russia during the Battle of the Palaces, Cameron enjoyed a brief revival of his career under Alexander I in 1803–1805. Apart from the well-researched Catherinian period (1779–1796), Cameron's life story remains poorly documented, not in the least due to Cameron's own efforts to shake off the bad reputation he had earned in the 1770s in London.
Document 7: Laurent-Benoît Dewez: Laurent-Benoît Dewez (14 April 1731 – 1 November 1812) was a Belgian architect of Walloon origin. He is considered the most influential architect in the Austrian Netherlands (present-day Belgium) from the second half of the 18th century. His architectural projects are of international stature and introduced a neoclassical style, with Italian and English influences, to the region. He designed a large number of châteaux, abbeys and churches in Belgium, many of which were damaged after the French Revolution.
Document 8: Visualization (graphics): Visualization or visualisation (see spelling differences) is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of humanity. Examples from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering and scientific purposes.
Document 9: Saint-Paul-Saint-Louis: Saint-Paul-Saint-Louis is a church on rue Saint-Antoine in the Marais quarter of Paris. The present building was constructed from 1627 to 1641 by the Jesuit architects Étienne Martellange and François Derand, on the orders of Louis XIII of France. Next door to it is the Lycée Charlemagne, also founded by the Jesuits. It gives its name to Place Saint-Paul and its nearest Metro station, Saint-Paul.
Document 10: Jacques Charles: Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a French inventor, scientist, mathematician, and balloonist.
Document 11: Architectural animation: Architectural animation is a short architectural movie created on a computer. A computer-generated building is created along with landscaping and sometimes moving people and vehicles. Unlike an architectural rendering, which is a single image from a single point of view, an architectural animation is a series of hundreds or even thousands of still images. When these images are assembled and played back they produce a movie effect much like a real movie camera except all images are artificially created by computer. It is possible to add a computer-created environment around the building to enhance reality and to better convey its relationship to the surrounding area; this can all be done before the project is built giving designers and stakeholders a realistic view of the completed project. Architectural renderings are often used along with architectural animation.
Document 12: Architectural reprography: Architectural reprography, the reprography of architectural drawings, covers a variety of technologies, media, and supports typically used to make multiple copies of original technical drawings and related records created by architects, landscape architects, engineers, surveyors, mapmakers and other professionals in building and engineering trades.
Document 13: Louis Le Chatelier: Louis Le Chatelier (20 February 1815 – 10 November 1873) was a French chemist and industrialist who developed a method for producing aluminium from bauxite in 1855. His son was the well known chemist Henri Louis Le Chatelier. His name is inscribed on the Eiffel tower.
Document 14: Technical illustration: Technical Illustration is the use of illustration to visually communicate information of a technical nature. Technical illustrations can be components of technical drawings or diagrams. Technical illustrations in general aim "to generate expressive images that effectively convey certain information via the visual channel to the human observer".
Document 15: Jean Baptiste Androuet du Cerceau: Jean Baptiste Androuet du Cerceau (1544/47–1590) was a French architect who designed the Pont Neuf (1579), spanning the Seine, Paris, and became supervisor of the royal works under Henri III and Henri IV, including the Louvre. Several "hôtels particuliers" are ascribed to him. The Hôtel d'Angoulême, the Hôtel de Lamoignon (1584), which houses the Historical Library of the City of Paris, and the Hôtel de Mayenne (rue St-Antoine in the Marais). The Hôtel de Mayenne, with rhythmically varied dormer windows set in a high slate roof, has the pediments of its piano nobile windows superposed on the frieze above.
