Danish Seismologist Inge Lehmann was apparenty
the Einstein of the Geology of the core of Earth:

Inge Lehmann - Wikipedia, the free encyclopedia

I stumbled across her while perusing the Wikipedia
article "Structure of the Earth".

if you read her Wikibio, you will learn as I did
(I had never heard of her before) that nobody
had any idea that the Earth had a solid core
until she came along.

I particularly enjoyed this quote from the link:

"Lehmann (Core Geology) was discovered through exacting scrutiny
of seismic records by a master of a black art for which no amount
of computerization is likely to be a complete substitute..."

She was a Dane, as my own father was, so I am
predisposed in her favor. I have a positive bias for her,
as I have for all Vikings.

Besides being smarter than 99.99999% of the rest
of us, she was also tougher than 99.99999%
of the rest of us, having lived a life
of 104 years, 9 months and 8 days duration (1888-1993).

Skoal! to the memory of Inge Lehmann.

Here are two more good bios on Professor Lehmann:

CWP at physics.UCLA.edu // Lehmann

(quote from link, emphasis added):

"I remember Inge one Sunday in her beloved garden ...with a big table filled with cardboard oatmeal boxes.
In the boxes were cardboard cards with information on earthquakes and the times for these and the times
for their registration all over the world. This was before computer processing was available, but the system
was the same. With her cardboard cards and her oatmeal boxes, Inge registered the velocity of propagation
of the earthquakes to all parts of the globe. By means of this information, she deduced new theories of the
inner parts of the Earth.

"It was not easy for a woman to make her way into the mathematical and scientific establishment
in the first half of the twentieth century.
As she said, `You should know how many incompetent men I had to compete with - in vain.' "

Bruce Bolt on Inge Lehmann

(quote from link, emphasis added):

She entered the University of Copenhagen in the autumn of 1907
and studied mathematics...for which she also needed physics,
chemistry and astronomy. She passed the first part of the examination
in 1910 and, in the autumn, was admitted to Newnham College, Cambridge, for a one-year stay...

She enjoyed her stay 'in spite of the severe restrictions inflicted
on the conduct of young girls, restrictions completely foreign
to a girl who had moved freely amongst boys and young men at home'.


Ha, ha- Danish girls like men and Danish boys like women,
which is how it should be and is best.
