In this time he worked on a stereo autograph for which he got a patent in
In 1935 he signed an agreement for manufacturing a new theodolite with
Kern Aarau, Switzerland.
After Heinrich Wild separated from Wild Heerbrugg and, in 1935 presented his
newest theodolite designs to Kern for manufacturing purposes, a completely new
line of theodolites was created.
All these instruments had several new features in common: Leveling cams
which turn on a horizontal axis for precise leveling, very stable, high
precision ball bearing vertical axis, glass circles with two concentric
graduations (double circle principle), powerful, short telescopes, fully
transitable, an overall very compact and rugged lightweight design. All these
features are still typical of today's Kern theodolites as confirmed by the two
theodolites DKM1 and DKM3 which, 40 years after their creation, are still a
mainstay in our present manufacturing program, even though several improvements
were added in the course of time.
Heinrich Wild did not limit his activity to the theodolite sector of Kern. He
developed an extraordinary dividing machine and laid the groundwork for mass
production of the new theodolites. Finally, in the year of his death, Heinrich
Wild contrived a photogrammetric plotter by seeking out an entirely new
approach. Even though this plotter appeared only as a prototype, Kern, with it,
ventured into the building of photogrammetric instruments.
The Swiss Geodetic Commission has issued a publication commemorating Heinrich
Wild. All contributions praise Dr. h.c. Heinrich Wild as a dominating, strong-
willed personality whose untiring energy was aimed at the only goal with
insistence and intensity; to develop more precise, lighter and smaller geodetic
instruments which would provide ease in handling and give more precise
measurement results in a shorter time.
