Postcard from Karl Friedrich Bonhoeffer to Georg Bredig
- 1929-Jun-21
Postcard from Karl Friedrich Bonhoeffer (1899-1957) to Georg Bredig (1868-1944) telling him that he will take part in a summer festival and explaining his schedule. On the postcard, Bredig credits Bonhoeffer for his work with hydrogen ions.
Bonhoeffer, along with fellow chemist Paul Harteck (1902 – 1985), discovered the spin isomers of hydrogen, orthohydrogen and parahydrogen. The two were the first to synthesize pure parahydrogen. This letter was written in the same year that Bonhoeffer made this discovery.

Sehr geehrter Herr Professor!
Vielen Dank für die liebenswürdige Zusendung des Programms. Ich werde natürlich mit grossem Vergnügen das Sommerfest mitmachen. Dagegen kann ich erst am 2ten vormittags ankommen, da ich am Montag noch Kolleg habe und die Nacht durchfahren muss. Ich sehe meinen Karlsruher Besuch mit grosser Freude entgegend bin. Mit den ergebensten Grüssen
Ihr

Dear Professor,
Thank you for kindly sending me the schedule. Of course, I will be delighted to take part in the summer festival. However, I can only arrive on the morning of the 2nd, as I still have to teach on Monday and then travel through the night. I look forward to my visit in Karlsruhe with great pleasure. Warm regards!
Yours,
K.F. Bonhoeffer
