In her summerhouse in Holte, Inge Lehmann created a comprehensive system of OTA Solgryn packages, where she kept her seismograms and measurements.

Filled with oatmeal packets

Inge Lehmann’s nephew, Niels Groes, who makes many trips to the summerhouse:

“I can remember Inge one Sunday in her beloved garden on Søbakkevej ... at a large table filled with oatmeal packages. In the packages were maps with information about earthquakes and the times they were registered all over the world. This was before there were computers, but the system was the same,” he recalls, adding:

“With her maps and oatmeal packages, Inge registered the speed of the spread of earthquakes around the world. It was against this background that she created new theories about the Earth’s interior,” explains Niels Groes.
