about me

After school I started my apprenticeship as a precision mechanic at Wild Heerbrugg  and so I came the first time into contact with surveying instruments in witch I fell fast in love.

Later I worked in Heerbrugg in various positions, in production, development, Quality Assurance and Technical Service. First, at Wild Heerbrugg and later with Wild Leitz, Leica AG and most recently at Leica Geosystems.

So I started early with my instrument collection and gradually also technical documentation were added.

Purpose and idea

Over the years I have collected many instrument and I also have a huge document collection. I am happy to share my knowledge with you, and in the online shop you will find many manuals, brochures, as well as service documents. I'm sure there is also something for you. 

On this web page you will find all sorts of information about: 

  • Heinrich Wild, his life story and its developments,

Its activities in the country's topography

with Zeiss, Jena

with Wild Heerbrugg and 

with Kern & Co. Aarau 

  • Wild Heerbrugg, its history, pictures from ancient times and information on the products 
  • Kern & Co, Aarau, its history, pictures from ancient times and information on the products 

I am happy to help you to identify your instrument and be dated. Clearly, I need a best picture and the serial number. 
If you have an interesting piece (document or instrument) have you no longer need, you make me an offer.

This is a private, nonprofit site.  If you would care to provide sponsorship and help defray expenses, please find contact information below.

Our Goals
are to share knowledge and provide you with as much information as possible, allowing you to enjoy your WILD instruments for many future years.
But I am also interested in nice old instruments for my private collection ... :-)

If you have any question, please contact me by email.

I'm please to help you.
