I've always thought that Francis Bacon was an interesting person and recently discovered that there is a memorial to him in Trinity College Chapel. What could be better but a cache to highlight his connection to Cambridge?
Below is the first section of a wikipedia page that describes his life, so that you can learn more about him.
Francis Bacon, 1st Viscount St. Alban, Kt., KC (22 January 1561 – 9 April 1626) was an English philosopher, statesman, scientist, jurist, and author. He served both as Attorney General and Lord Chancellor of England. Although his political career ended in disgrace, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method during the scientific revolution. Bacon has been called the creator of empiricism. His works established and popularised inductive methodologies for scientific inquiry, often called the Baconian method, or simply the scientific method. His demand for a planned procedure of investigating all things natural marked a new turn in the rhetorical and theoretical framework for science, much of which still surrounds conceptions of proper methodology today. Bacon was knighted in 1603, and created both the Baron Verulam in 1618 and the Viscount St. Alban in 1621; as he died without heirs, both peerages became extinct upon his death. He famously died by contracting pneumonia while studying the effects of freezing on the preservation of meat.
Sorry for the size of the cache - using up birthday presents!
