Dear all,
It is sad to hear of such a loss... However, he still lives fully in his
published (and unpublished) work and through all who interacted with him :)
I met Uli in person once, in 2002, for a couple hours and he stroke me as a
very interesting character.
After I asked him how coherence issues were taken into account in the
evaluation of diffraction intensities, he opened a great smile and said "At
a certain point in time I did some calculations in that direction and
concluded that there should be no diffraction at all in the first place and
yet I made a career out of diffraction. It is something that should be taken
care of better." And he added - "You only need a small aperture at a long
distance from the anode. It's all there to explore."
He was working with Rigaku at that moment and his talk was about cryocooled
point source anodes. And he mentioned that the promises for better and
cheaper x-ray home sources in the future resided in somebody inventing a
device that would be useful for mobile companies, so they would invest the
money to develop the technology and mass produce it and make it cheap. And
we could use it as a by-product. This is MX back to its early days of
parasitic operation in particle accelerators.
Anyway, I remember that at that same meeting Andrew Leslie showed the
original oscillation camera designed by Uli. Nice piece of kit :) That is
another little memento we can keep and remember his achievements.

All crystallographers who knew him will be sad to hear that Uli Arndt died
last night, aged 81 from cancer which developed during the last few months.

This is the notice which has been posted in the MRC Laboratory of Molecular
Biology:
Uli was recruited by Max Perutz from the Royal Institution and joined LMB
when it opened in 1962, in order to bring expertise in instrumentation
development, particularly for X-ray crystallography. This was at a stage
when far less equipment was available commercially and scientific advances
depended almost entirely on developments within the Lab. In this Uli was
very successful, pioneering a series of X-ray diffractometers, the
Arndt-Wonacott rotation camera, film scanners, the FAST X-ray detector and
most recently a miniature microfocus X-ray source. He also co-authored two
influential monographs on Single Crystal Diffractometry and on The Rotation
Method in Crystallography, and recently completed his autobiography. He
won the BCA Dorothy Hodgkin prize and gave the accompanying lecture in 2000
on Crystallographic Apparatus: Past, Present & Future
Uli had wide interests, including sketching and hiking, and had an
encyclopaedic knowledge of history, freely shared over coffee or lunch in
the Canteen. He was an accomplished raconteur, and a sympathetic and
helpful listener.
We shall all miss his entertaining company and stimulating conversation.
