[what is this?]

Frans Louis Henri Marie Stumpers was born in Eindhoven, Netherlands, on 30 August 1911. (1) He was champion of the Eindhoven Chess Club in 1938, 1939, 1946, 1947, 1948, 1949, 1951, 1952, 1953, 1955, 1957, 1958, 1961 and 1963, (2) and the champion of the North Brabant Chess Federation (Noord Brabantse Schaak Bond, NBSB) in 1934, 1935, 1936, 1937, 1938, 1939, 1940, 1941, 1942, 1943, 1944, 1946, 1948, 1949, 1950, 1951, 1952, 1953, 1954, 1955, 1959, 1961, 1962, 1963, 1964, 1965, 1966 and 1967. (3) He participated in five Dutch Chess Championships, with a 4th place in 1948, (4) and represented his country at the 1st European Team Championship, in Vienna in 1957 (two games, vs Josef Platt and Max Dorn). (5) From 1945 and until about 1956, he was first Secretary and then Chairman of the NBSB. (3)

Stumpers was a physicist, and worked for the Philips company as an assistant from 1928. During 1934-1937, he studied at the University of Utrecht, where he took the master's degree. (6) In 1938 he was again employed at Philips, (6) and at a tournament in 1942, he supplied the hungry chess players with food from his employer. (3) After the war, he made a career in physics, with patents and awards on information ('radio') technology. He received degrees from several universities and colleges, including in Poland and Japan. (1, 3, 6) He retired from Philips in 1972, but continued teaching, (6) partly as professor at the University of Utrecht (1977-1981). (7) He was also Vice President (1975-1981) and Honorary President (1990-2003) of URSI, the International Union of Radio Science. (8)

Louis Stumpers married Mieke Driessen in 1954. They had five children, three girls and two boys. (6)

  HeMateMe: Yeah, in the same vein I was pretty sure the somewhat old and creaky Dallas Mavs had no chance of repeating. Dirk, Jason Kidd--when you shove 35 year old guys into young guy minutes, you get injuries and lost games.

It might be a breakout year for the Thunder, although Miami looks like they are really starting to put it together. Hard to see anyone from the west beating Miami in the finals.

Premium Chessgames Member
  HeMateMe: Not Swept! The Knicks win, 89-87!. Now, they just have to bring the same energy for 3 more games. where's 'Oak when you need him?
Premium Chessgames Member
  Jim Bartle: Or Anthony Mason. He could shake things up at least.
Premium Chessgames Member
  HeMateMe: You don't "want Mace-In-your-Face" as they used to say, back in the day.

Spike Lee's fan costumes, at the Garden, are horrible. The dunking stool of the Salem witch trials should be brought back, so Spike could be given a ride.

May-07-12  talisman: winning MLB pitcher went 0 for 8 at the plate yesterday. hasn't happenned since 1905. who is he?
Premium Chessgames Member
  WannaBe: Baron Davis.
May-07-12  talisman: laughed out loud! davis is correct!!! and the Baron i am a fan of...ole new orleans player and our best...i guess we all know now it's chris davis of the O' the way the 1905 guy was Rube Waddell...would leave the mound...jump the fence...take off...anytime he heard the fire truck siren!
Premium Chessgames Member
  WannaBe: Good thing it wasn't the ice cream truck.
Premium Chessgames Member
  HeMateMe: Have the Cubbies been mathematically eliminated yet?
Premium Chessgames Member
  WannaBe: Since Ground Hog Day.
Premium Chessgames Member
  HeMateMe: Ok, only two players have a home run THREE TIMES in a World Series game 7. One name is easy; the other is less well known.
Premium Chessgames Member
  Jim Bartle: The less well-known one just died, I think.
May-08-12  talisman: guessing now...Ruth, Mantle, Gehrig, Maris, or least 3 of these are wrong :)
Premium Chessgames Member
  HeMateMe: Of course, Yogi, and JB has the other one. [that was quick]

  HeMateMe: Ryan Leaf, Quarterback/criminal, takes a plea deal.


Just nine months, in a rehab facility. I guess this is his last chance; he'll get real jail time next go around.

As some of the Rogoff regulars would point out, if this was some african american guy from Detroit, a four-time loser, like Ryan is, he would be doing a nickel in the state pen, or something like that. Ryan is quite lucky.

  HeMateMe: Lakers and Nuggets (Nuggets?) are tied now at 3-3. The Fakers might not even make it out of their first round series. End of a dynasty?

What about albert Pujols? ten year $240M contract, and he's hitting .198! I could do that.

May-12-12  King Death: <HMM> A lot of white guys that aren't former "names" would be in the same boat for at least that nickel.
May-12-12  King Death: Wilt vs. Elgin 1957, one for the ages:

Premium Chessgames Member
  Shams: Ryan Leaf still faces prison time in Texas. The plea deal he got was for the Montana charges only.
Premium Chessgames Member
  Jim Bartle: That's a heck of a story on the playground Wilt-vs.-Baylor games. I wish it had a little more on the games themselves, and especially about Baylor's playing style. It was different from anybody playing today.
May-13-12  King Death: Ivan Johnson has talent:

$25 grand for somebody that's a rookie out of D league is a lot of dough, you'd think he could control himself some.

  WannaBe: On one side of the river stands 3 cannibals, on the other side of the river stands <technical draw>, <WannaBe>, and <NakoSonorense>.

If the cannibals outnumbers the member(s), they will be attacked, and eaten. There is a canoe, but it can only hold 2 person, (minimum one person have to row).

How much money do I have in my wallet?

You must have at least $20 to pay for use of my copyrighted name.

  HeMateMe: SuperBowl Shuffle quarterback is being sued by the FDIC:


I don't think I've ever heard of an athlete beind sued by the FDIC, those who guarantee bank deposits. Jimmy Mac, who once mooned a media helicopter on a golf course, is also part of the players suit against the NFL regarding concussions in pro football.

Premium Chessgames Member
  Jim Bartle: So he can use the concussion suit to defend himself in the FDIC lawsuit.
