Dear Adolf Erik Nordenskiöld,
Greetings from your native country where snowless and slush covered early winter sceneries are becoming increasingly typical. Please allow me to call you by your first name despite your noble lineage.
Dear Alexander von Humboldt,
If you were still with us, I would wish you happiness on this quarter-millennial anniversary of your birth. Could you have guessed that your memory would live on for centuries? Or perhaps you were hoping for this honour which, admittedly, no researcher could refuse.
