#lastseen Image Research Plattform

Concept, Product Design and Development for the #lastseen atlas making holocaust research accessible.

Unveiling History: A plattform to connect regular users and scientists to history's lessons.

Building a digital research platform

The #lastseen Atlas is a digital archive that brings together Holocaust-era photographs from Germany in one accessible platform. We designed it so researchers, historians, and everyday readers can explore rare evidence of this dark chapter in history without getting lost in scattered resources.

By focusing on simplicity and impact, we help preserve these images—and their stories—so they’re never forgotten. The plattform was featured in world-leading publications from The Guardian to the SZ and has gathered over 500.000 pages views in just over a year.

As the #lastseen atlas continues to grow through new discoveries and research, it is being featured in world-renowned publications like the Guardian, SZ and Haaretz. This proves our ambition to make research accessible by millions. Since its launch, the product has attracted over 500.000 views.
