Dr. Dietmar Hager – Keynote speaker with a view of the universe

06. January 2026 – Mandy Weinand

When an experienced hand surgeon takes to the stage to talk about team leadership, motivation and vision, it sounds unusual at first. But it is precisely this extraordinary combination that astrophotographer Dietmar Hager embodies.

As a medical professional, he is familiar with the world of microscopes, precision and responsibility. As a speaker, he takes his audience on an inspiring journey – from the microcosm of the operating theatre to the macrocosm of the stars.

What can a company learn from the universe?

The universe is a gigantic system in which order and chaos intertwine in a fascinating way. Stars are born, planets form, galaxies collide – and yet everything follows certain principles.

Dietmar Hager shows that every company exhibits similar dynamics:

  • Networks instead of lone warriors – like stars that form clusters.
  • Constant development – those who stand still burn out.
  • Recognising interactions – every change has an impact on the entire system.

Looking at the universe allows us to draw surprising conclusions about team culture and organisation.

A journey through the cosmos – what does this have to do with team motivation?

Motivation arises when people recognise meaning and become part of a larger mission.

Like galaxies, which consist of millions of individual stars, a team also thrives on many individual forces that together create something greater:

  • Every employee is a shining star.
  • Leadership provides orientation like constellations.
  • Cohesion creates gravity.

Hager makes it clear: those who know their place in the ‘company galaxy’ system work with greater commitment, creativity and purpose.

Dietmar Hager – from surgeon to astronomer

The transition from surgical work to astronomical observation is more than just an image – it describes Hager’s way of shifting perspectives.

In the operating theatre, he works in the millimetre range, analyses tiny structures and takes responsibility in the microcosm of the body. As a lecturer, he opens our eyes to the stars and shows how helpful it is to look beyond our own limitations.

This gives rise to valuable insights:

  • Precision in detail, vision in the big picture
  • The courage to look up and discover new things
  • Recognition that small changes can have a big impact

From microcosm to macrocosm

The interplay between both worlds becomes a leitmotif for Hager.

What can the smallest detail trigger in a process? How are decisions in a company related to major developments?

The message is:

  • Those who understand the small understand the big – and vice versa.
  • A change of perspective opens up solutions.
  • The microcosm and macrocosm follow principles that we can use.

As a keynote speaker, Dietmar Hager succeeds in combining medical precision with astronomical breadth – and using this to generate ideas for companies.

He inspires teams to think bigger, recognise connections and reflect on their own contribution to the larger system. A journey into the cosmos that does not lead into space, but right into the heart of the central question of successful collaboration:

What do we learn when we shift our gaze from the microcosm to the macrocosm?
