A very successful businessman...
A very successful businessman had a meeting with his new son-in-law. I welcome you into the family,” said the man. “To show you how much we care for you, I am making you a 50-50 partner in my business. All you have to do is go to the factory everyday and learn the operation.”
The son-in-law interrupted. “I hate factories. I can’t stand the noise.” “I see.” replied the father-in-law, “Well, then you’ll work in the office and take charge of some of the operations.” “I hate office work,” said the son-in-law. “I can’t stand being stuck behind a desk.” “Wait a minute,” said the father-in-law. “I just made you half owner of a money-making industry, but you don’t like factories, and won’t work in an office. What am I going to do with you?” “Easy,” said the son-in-law. “Buy me out.”

Edward ForbesDied 18 Nov 1854 at age 39 (born 12 Feb 1815). British naturalist, pioneer in the field of biogeography, who analyzed the distribution of plant and animal life of the British Isles as related to certain geological changes. Forbes is considered by many to be the founder of the science of oceanography and marine biology, especially mollusks and starfishes. He participated in dredgings and expeditions in the Irish Sea (1834), France, Switzerland, Germany, Algeria (1836), Austria (1838), and the Mediterranean (1841-42). During this period, he pursued the study of life in the littoral zones (the ocean from the shore to the continental shelf) and developed an interest in the geographical distribution of animals. His study of the fauna of the Aegean Sea stimulated interest in marine biology. Unfortunately, he is best known for his “azoic theory” (1843), which stated that marine life did not exist on sea beds at depths over 300 fathoms (1800 feet). This was soon to be disproved, (but the desire to test this hypothesis has led to further exploration until, eventually, no depth has been completely unstudied). He became paleontologist to British Geological Survey in 1844. |
