GAUTIER
 
Paul, Ferdinand
(1842-1909)
 
 Instrument  maker  
    Born in Paris in  a modest
family,
Paul Gautier, started to work
as an apprentice at the age of  13. Five years later, he was 
a worker  in the
Secrétan's manufacture,
then,  in 1866,  he moved to the workshop of  Wilhem
Eichens   to whom he succeeded   later on.
   
His  instruments are closely related to the
tendencies of the
astronomy of the end of the XIXth century,  and are 
remarkable for  the realization of  its  screws,  
graduated dials and mountings of telescopes. He 
provided most of the astrographs dedicated to  the  "Carte du
Ciel"  (Sky Chart). The  first sample was made  to 
his   own expense, in 1885.  
His
expertise had no equivalent in France in this field.  Most of the
large instruments that  equipped   the French observatories
came out of  his  workshop. His most  important 
devices included equatorial and coude 
refractors,  telescopes. They were built for French, 
Austrian, Greek, Dutch, Vatican, Spanish,  Algerian, Argentine,
and  Brazilian  observatories.   
    
His  career of honest, generous and
disinterested man, ended by  a
regrettable failure. He built the largest refractor ever made, for
the Paris Great Exhibition  of 1900. The
lenses of 49 inches (132 cm) of diameter were assembled at the end
of a horizontal, long tube of more than 195 feet (62m) connected to a
large
siderostat. However, this realization turned out to be a financial
disaster  that ruined the
manufacturer, because it failed to run. After several
adjustments,  the
instrument could have played an important role in research, but it
was 
unfortunately dismounted and its components were sold. 
Member of the Bureau des  Longitudes (1897).
