The price of a piece of history

A fresh lemon can be purchased for less than $1. But in 2008, Cowan's Auctions in Cincinnati sold a lemon blackened with age for $2,350.

What was so special about this lemon?     1     According to a handwritten note in ink attached to a partly sealed bottle containing the lemon, the fruit was picked in May 1842 by Washington's "old gardener" some 43 years after the first president's death

Two thousand dollars is a lot to pay for produce, even from the estate of a founding father. This sale, however, just might be considered a bargain compared with prices paid for other historical collectibles in recent years.     2    

Collecting a piece of history, or an object associated with a famous person, is not brand new. Ordinary objects with extraordinary stories have increasingly been coming to auction and achieving high prices, says Thomas Venning, director of Christie's department of books and manuscripts in London. Prices are being driven up, he says, by collectors in the U.S. and, increasingly, in Asia. The Hawking wheelchair, for example, was purchased by a private museum in China.

    3     For one thing, their history of ownership is both crucial and sometimes difficult to prove. Photographs of the famous person with the object, as well as documentation (such as letters, diaries or recollections by acquaintances referring to the object) can also help.       4     To evaluate the value of a Picasso painting, one can look at recent prices paid for other Picasso paintings of the same period, similar size or style. Finding another recent sale of a lemon planted by George Washington is a different matter.

Katie Horstman, head of Cowan's American History department, says she could find no comparable items for the lemon as she prepared the piece for its auction. Ms. Horstman nevertheless eventually arrived at the estimated value at $3,000 to $4,000, she says, by researching auction records for objects somehow associated with Washington that had appeared on the market.

Cowans ended up estimating the value of the lemon at $3,000 to $4,000, according to description on its website. Objects associated with Washington these days, Ms. Horstman says, can sell for anywhere from 1,000 up to tens of thousands of dollars.

A．Stephen Hawking’s wheelchair fetched 296, 750 at a sale at Christie's in London last November.

B．Yet determining potential values of such objects isn't easy.

C．It was said to be from a tree planted by George Washington at Mount Vernon.

D．The auction result surely drew the attention from both the business and economics worlds.

E．The uniqueness of many of these objects further complicates efforts to put a value on them.

F．Therefore the unique value of many objects proved the worth of collection.

3 . Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.

Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognised in the form of a Military Medal by the French government.

In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity (辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.
