In Otto Loewi stimulated the heart of a frog with electrical impulses and had it pump a small amount of nutrient solution.

When the fluid was transferred to another heart, it operated in a similar way. This provided proof that chemical substances convey nerve signals to organs. He then had a dream in which he visualized an experiment that could put an end to the debate over how nerves communicated with one another.

He woke up in the middle of the night, scribbled some notes about this potentially groundbreaking experiment, and then fell back to sleep. To his great frustration, however, when he awoke again he couldn't read the notes he had written. The following night, he woke up at 3am after again dreaming about the experiment. This time he didn't dare risk losing his ideas to illegibility, so he rushed off to the lab to try the experiment.

Loewi isolated two beating frog hearts vertebrate cardiac muscle will continue to contract even after being removed from the body and filled them with a saline solution.

Then, he stimulated the vagus nerve in one of the hearts, a procedure that slows the heart rate. He took the saline solution from the heart whose vagus nerve he had stimulated, and applied it to the second heart. This caused the rate of the second heart to slow down. He arrived in the United States in In America Loewi came into close contact with many outstanding biologists from all over the world and here he found much inspiration for his work. In he was appointed Foreign Member of the Royal Society.

Since his schooldays, Loewi showed keen interest in the humanities. He always enjoyed music, architecture, and painting, and in his younger years seldom missed an opportunity to visit museums and exhibitions. In he married Guida Goldschmiedt, daughter of Dr.

They had three sons, Hans, Victor, Guido; and one daughter, Anna. Professor Loewi became an American citizen in He died December 25, It was later edited and republished in Nobel Lectures.
