David Ji
David Longfen Ji is an American businessman who co-founded Apex Digital, an electronics manufacturer.
In 2004, he was arrested in China following a dispute with Sichuan Changhong Electric, a supplier owned by the city of Mianyang and the province of Sichuan.
Changhong accused him of defrauding them through bad checks.
Ji was taken, according to an account by his lawyer, to the senior management and told, "I decide whether you live or die."
He has been held in China without charges.
Ji's case highlighted an "implicit racism" in dealings with American businessmen.
As a U.S. citizen he was not granted the same treatment by authorities as non-ethnically Chinese businessmen sharing the same nationality.
Ola Brunkert
Ola Brunkert( 15 September 1946 – 16 March 2008) was a Swedish drummer who was one of the main session drummers for the pop group ABBA.
Brunkert and bassist Rutger Gunnarsson are the only two side musicians to appear on every ABBA album.
Born in Örebro, Sweden, Brunkert played with Slim's Blues Gang, before joining the pop group Science Poption.
He then formed the jazz- rock combo Opus III with the guitarist Janne Schaffer and by 1970 had become one of the most sought after session drummers in Stockholm.
He was not among the four members of ABBA whose faces adorned the album covers, but was a key supporting musician for the group as it achieved stardom.
Brunkert played on the group's first single" People Need Love", their Eurovision hit" Waterloo", and consistently on a great many of their recordings throughout the 1970s.
ABBA promised that" one day we ’re gon na let you hear him sing" in the liner notes for the album" Arrival" in 1976.

He appeared on stage with ABBA at the Eurovision Song Contest 1974 and played with them on their concert tours of Europe and Australia in 1977, North America and Europe in 1979 and Japan in 1980.
As reported in" The Times" of 18 March 2008, he bought a property in the Betlem housing complex in Artà, Majorca, Spain, in the 1980s and lived there for the remainder of his life.
It was at his home that he died, less than a year after the death of his wife, Inger, in 2007.
Brunkert died after an accidental fall at the age of 61.
He was found with cuts on his neck, causing initial suspicion as to his death.
Brunkert had hit his head against a glass door in his dining room, shattering the glass and cutting himself in the neck.
He had managed to wrap a towel around his neck and leave the house to seek help, but collapsed in the garden.

J. Arthur Seebach Jr.
J. Arthur Seebach Jr( May 17, 1938 – December 3, 1996) was an American mathematician.
Seebach studied Greek language as an undergraduate, making it a second major with mathematics.
Seebach studied with A. I. Weinzweig at Northwestern University.
He earned a Ph.D. with the thesis" Cones and Homotopy in Categories".
Seebach began to teach at Saint Olaf College in Northfield, Minnesota in 1965.
He, his wife Linda A. Seebach, and Lynn A. Steen wrote an expository article" What is a Sheaf".
The paper showed that a sheaf is useful in analysis, algebra, and geometry when considering germs of holomorphic functions, local rings, and differential forms.
J. Arthur also wrote" Injectives and Homotopy".
In 1971 Seebach and Steen took over the Book Reviews section of American Mathematical Monthly, including Telegraphic Reviews which ran for several pages every month.
The massive effort was eventually distributed over some 50 mathematicians at Saint Olaf, Carleton, and Macalester Colleges.
Telegraphic
Reviews, in telegraphic style, was started by Kenneth O. May in 1965 and provided an American posting of new publications before the digital age.
Seebach and Steen conducted research in a 1967 summer school with students investigating the independence of conditions on topological spaces.
They summarized their work in Counterexamples in Topology( 1978).

Beyond mathematics, Seebach sang with the Bach Society of Minnesota.
The craftsmanship of the Studebaker automobile appealed to Seebach and he operated a side- business in Studebaker parts, driving some, and publishing a newsletter for fellow aficionados of the car.
His newsletter experience was of value to Mathematical Association of America when they began their own newsletter.
Seebach died in 1996 from complications of diabetes.
