Fritz Pregl

Died 13 Dec 1930 at age 61 (born 3 Sep 1869).Austrian chemist awarded the 1923 Nobel Prize for Chemistry for developing techniques in the microanalysis of organic compounds. Pregl began research on bile acids in about 1904. With only tiny yields to study, he pioneered techniques of microanalysis. Whereas Justus von Liebig had needed about 1 gram of a substance before he could make an accurate analysis; through his new techniques, Pregl could work with 2.5 milligrams. This was achieved by the careful scaling down of his analytic equipment and the design of a new balance (produced in collaboration with the instrument maker W. Kuhlmann of Hamburg) capable of weighing 20 grams to an accuracy of 0.001 milligram. His techniques are of immense importance in organic chemistry.

The lawyer was cross-examining

The lawyer was cross-examining a witness.
“Isn’t it true, “he bellowed, “that you were given $500.00 to throw this case?”
The witness did not answer. Instead, he just stared out the window as though he hadn’t heard the question. The attorney repeated himself, again getting the same reaction - no response.
Finally, the judge spoke to the witness, “Please answer the question.”
“Oh,” said the startled witness, “I thought he was talking to you.”
