The coverage of Onassis is fine.There are maybe 3 other bio's on him ,so if you want to know about him,there is much to read.Livanos and Niarchos are little known and that is unacceptable.In the end Livanos and Niarchos acquired more wealth than the more known Onassis.Livanos,a very frugle man lived modestly given his means.He did'nt like borrowing money so he paid cash for his ships.He switched to credit purchases years later.Onassis & Niarchos married his two daughters.Niarchos was like an aristocrat.He collected the finest of all types of art.His collection at one point was worth over a $100 million.He lived very well given his means.Women adored him.All three men are dead now ,Niarchos' pile of wealth reached upwards of $2.5 billion he lived close to his 90's.These three changed the transport of oil and commodities by always building bigger and better ships.Great history ,great read.
