Koechlin, Nouguier and Sauvestre · shared design
People and actions
SETE dates Maurice Koechlin’s first sketch to June 6, 1884. He developed the tower idea with engineer Émile Nouguier; architect Stephen Sauvestre then helped reshape its appearance. Gustave Eiffel supported and advanced the revised project. The operator also records Koechlin’s supervision of calculations, foundations and construction.
What to remember
Remember the different skills and contributions behind a monument bearing one name.
What this record does not establish
This is the operator’s historical account, not the complete design archive or an allocation of individual credit. The 1884 sketch is not the final built design.
Institutional record · The author of the first sketch; Gustave Eiffel finally convinced: sketch dated 6 June 1884; Nouguier, Sauvestre and Eiffel roles
Time precision · Date only; exact time not establishedStart of pillar assembly, used as a reference for the 1887–1889 construction period; not the date of every worker’s task.
Workshop crews and riveters · making the joints
People and actions
Parts were prepared at Levallois-Perret before assembly on site. SETE distinguishes 150 factory workers from the 150–300 workers on the building site. Its riveting account describes four cooperating roles: heating, holding, forming the head and hammering. These are different workplaces and a task team, not one combined workforce total.
Facts and scope
Workers at the Levallois-Perret factory
150people
Factory workforce in SETE’s construction summary; separate from the on-site range, not the total unique workers over the project.
Precision depended on preparation and cooperation across the workshop and the building site.
What this record does not establish
The figures are the operator’s construction summary, not a complete payroll, daily headcount or list of worker names. No individual shift, route or injury record is reconstructed.
Time precision · Year onlyYear the operator gives for the start of the twentieth painting campaign, not the date of every named contribution or its completion. Related 3D remains at 1889.
Painters, safety specialists and conservation architects
People and actions
SETE describes surface diagnosis, preparation, repair and protective coats applied by hand. Specialists first install lifelines and safety nets. Its account of the twentieth campaign names architect Pierre-Antoine Gatier, project manager Marion Gauchard, Jarnias and Atelier de France, alongside paint conservators and laboratory support studying old paint layers and archives.
What to remember
Preservation depends on repeated skilled care and on protecting the people who do it.
What this record does not establish
These are institutional descriptions, not a worker roster or an independent safety audit. A campaign plan does not establish completion, full paint removal or the present condition of every member. The 1889 scene does not depict this modern campaign.
Institutional record · Painting campaign and published text transcript: Pierre-Antoine Gatier, project manager Marion Gauchard, Jarnias, Atelier de France, archives, paint-layer study and worker protection; contemporary plans are not completion evidence

Time precision · Year onlyYear of the North elevator’s return; daily care spans other years. The linked scene shows only the completed 1889 structure, not the modern elevator or this work.
Elevator technicians and operators · everyday care
People and actions
SETE describes technicians checking and starting the elevators before visitors arrive, monitoring operation, lubricating and replacing parts; operators manage visitor flow. For the North elevator’s return in 2024, it credits Baudin-Châteauneuf with controls, automation and mechanics, and Eiffage Métal with structural work. Updated maintenance and troubleshooting systems also support the service teams.
What to remember
A landmark remains usable through daily inspection, repair and the work of people beyond its original builders.
What this record does not establish
The sources do not name every technician or provide complete shift and inspection logs. The 2024 return is one elevator milestone, not completion of all maintenance or a present-day safety certification by this project. Modern machinery is not reconstructed in the 1889 scene.
Institutional record · The elevators today: technicians check and start machinery before opening, monitor operation; elevator operators manage visitors
