Problem: Rockefeller was the second of six children and eldest son born in Richford, New York to con artist William Avery "Bill" Rockefeller (November 13, 1810 - May 11, 1906) and Eliza Davison (September 12, 1813 - March 28, 1889). His siblings were Lucy (1838-1878), William Jr. (1841-1922), Mary (1843-1925) and twins Franklin (Frank) (1845-1917) and Frances (1845-1847). His father was of English and German descent while his mother was of Scots-Irish descent. Bill was first a lumberman and then a traveling salesman who identified himself as a "botanic physician" and sold elixirs.

In 1859, Rockefeller went into the produce commission business with a partner, Maurice B. Clark, and they raised $4,000 ($108,948 in 2017 dollars) in capital. Rockefeller went steadily ahead in business from there, making money each year of his career. While his brother Frank fought in the Civil War, Rockefeller tended his business and hired substitute soldiers. He gave money to the Union cause, as did many rich Northerners who avoided combat. Rockefeller was an abolitionist who voted for President Abraham Lincoln and supported the then-new Republican Party. As he said, "God gave me money", and he did not apologize for it. He felt at ease and righteous following Methodist preacher John Wesley's dictum, "gain all you can, save all you can, and give all you can."  At that time, the Federal government was subsidizing oil prices, driving the price up from $.35 a barrel in 1862 to as high as $13.75. This created an oil-drilling glut, with thousands of speculators attempting to make their fortunes. Most failed, but those who struck oil did not even need to be efficient. They would blow holes in the ground and gather up the oil as they could, often leading to creeks and rivers flowing with wasted oil in the place of water.  In this environment of wasteful boom, the partners switched from foodstuffs to oil, building an oil refinery in 1863 in "The Flats", then Cleveland's burgeoning industrial area. The refinery was directly owned by Andrews, Clark & Company, which was composed of Clark & Rockefeller, chemist Samuel Andrews, and M. B. Clark's two brothers. The commercial oil business was then in its infancy. Whale oil had become too expensive for the masses, and a cheaper, general-purpose lighting fuel was needed.  While other refineries would keep the 60% of oil product that became kerosene, but dump the other 40% in rivers and massive sludge piles, Rockefeller remained as thrifty and efficient as ever, using the gasoline to fuel the refinery, and selling the rest as lubricating oil, petroleum jelly and paraffin wax, and other by-products. Tar was used for paving, naphtha shipped to gas plants. Likewise, Rockefeller's refineries hired their own plumbers, cutting the cost of pipe-laying in half. Barrels that cost $2.50 each ended up only $.96 when Rockefeller bought the wood and had them built for himself.  In February 1865, in what was later described by oil industry historian Daniel Yergin as a "critical" action, Rockefeller bought out the Clark brothers for $72,500 (equivalent to $1 million in 2017 dollars) at auction and established the firm of Rockefeller & Andrews. Rockefeller said, "It was the day that determined my career." He was well positioned to take advantage of postwar prosperity and the great expansion westward fostered by the growth of railroads and an oil-fueled economy. He borrowed heavily, reinvested profits, adapted rapidly to changing markets, and fielded observers to track the quickly expanding industry.

Question:
Hardy Rodenstock (born December 7, 1941 in Marienwerder (Kwidzyn), legal name Meinhard Gorke ) is a former publisher and manager of pop and Schlager music in Germany and is a prominent wine collector, connoisseur, and trader, with a special interest in old and rare wines. He became famous for his allegedly uncanny ability to track down old and very rare wines, and for arranging extravagant wine tastings featuring these wines. It has been alleged that Rodenstock is the perpetrator of an elaborate wine fraud. In 1992, a German court found that Rodenstock had "knowingly offered adulterated wine" for sale.
In May 2008, a book about the controversy was published under the title The Billionaire's Vinegar, written by Benjamin Wallace. In the book a tritium test and two carbon-14 tests date the wine circa 1962. Later, a cesium-137 test gave similar results. Rodenstock was not available for comments on the publication of the book. Auctioneer Michael Broadbent, on the other hand, was unhappy with how his relationship to Rodenstock was portrayed in the book.  In July 2009 it was announced that Michael Broadbent would sue Random House, the publishers of The Billionaire's Vinegar, for libel and defamation of character, on claims that the book made allegations that suggested that Broadbent had behaved in an unprofessional manner in the way in which he had auctioned some of these bottles and that his relationship and dealings with Hardy Rodenstock was suspected of being improper. The suit was filed in the United Kingdom, whose libel laws are favorable to the plaintiff. Unlike U.S. law, in English defamation law even true allegations can be defamatory. Random House initially stated it did not believe it had defamed Broadbent and would defend the lawsuit.  In October 2009, Random House, avoiding trial, entered into a settlement agreement with Broadbent. In a statement read out in open court, Random House apologised unreservedly for making the allegations, and accepted that they were untrue. It gave an undertaking not to repeat the allegations and paid Broadbent undisclosed damages. It removed the book from sale in the United Kingdom. It also was reported that Wallace was not a party to the lawsuit or settlement, that Random House would be making no changes to the book, and that it would continue to publish the book in all territories except the UK.  The film rights to The Billionaire's Vinegar have been purchased by a Hollywood consortium, while HBO simultaneously had bought the film rights to the corresponding The New Yorker article.
