For organizing a lecture we’ll need the following data:

  • Exact time (day, hour)
  • Exact location (postal code, town, street, house number)
  • The topic, you wish me to talk about
  • Responsible contact person (name, phone number, e-mail-address)

An appointment for a lecture is committing for both sides if registered on the list of upcoming events on our website.

Please, as an organizer of an event check all data of your event – and let us know immediately if you find any inaccuracies or misunderstandings.

Portrait images of Johannes, also for publication purposes, may be downloaded directly from Perry Trotter Photography. Please, attribute to “Perry Trotter”.

We are grateful if organizers provide us with accommodation for the night after the event, in a hotel or in a comparable private accommodation that offers privacy.

For further questions or suggestions for this page, you are welcome to contact us.
