Hope's Apparatus    Thomas Charles Hope (1766-1844) was the Professor of Chemistry at Edinburgh University from 1795-1843. In 1805 he published a paper "Experiments and Observations upon the Contraction of Water by Heat at Low Temperatures". In it he showed that water has its maximum density at about 4°C, a fact well known to fish who congregate at the bottom of ponds in freezing weather.     The apparatus at the left is at Kenyon College, and at the right is an example of Hope's apparatus at the University of Cincinnati.

In 1815 Hope was elected as president of the Royal College of Physicians of Edinburgh(1815–19), and as vice-president of Royal Society of Edinburgh (1823–33) during the presidencies of Walter Scott and Thomas Makdougall Brisbane.

He founded a chemistry prize at the University of Edinburgh.[2]

Charles Darwin was one of Hope's students, and Darwin viewed his chemistry lectures as highlights in his otherwise largely dull education at the University.
