Problem: Columbus Delano, (June 4, 1809 - October 23, 1896) was a lawyer, rancher, banker, statesman and a member of the prominent Delano family. Delano was elected U.S. Congressman from Ohio, serving two full terms and one partial one. Prior to the American Civil War, Delano was a National Republican and then a Whig; as a Whig he was identified with the faction of the party that opposed the spread of slavery into the Western territories, and he became a Republican when the party was founded as the major anti-slavery party after the demise of the Whigs in the 1850s. During Reconstruction Delano advocated federal protection of African-Americans civil rights, and argued that the former Confederate states should be administered by the federal government, but were not part of the United States until they met the requirements for readmission to the Union.

On his resignation from Grant's cabinet, Delano returned to Mount Vernon where for the next twenty years he served as president of the First National Bank of Mount Vernon. He was a longtime trustee of Kenyon College, which awarded him the honorary degree of LL.D.; among his charitable and civic donations was his endowment of Kenyon's Delano Hall; this building was in use until it was destroyed by a fire in 1906. His Lakeholm mansion, built in 1871 at the outskirts of Mount Vernon, is now part of Mount Vernon Nazarene University.  On April 3, 1880, John W. Wright, a judge from Indiana, was convicted at trial of having assaulted Delano on a Washington, D.C. street corner on October 12, 1877. Wright, who had been an Indian Agent in the Interior Department while Delano was Secretary, had been convicted of fraud, and blamed Delano. On the day of the assault he was in the company of Walter H. Smith, formerly Solicitor of the Department of the Interior; Wright was accused of provoking a fight by questioning Delano's honesty as Secretary of the Interior, and then striking Delano with his walking stick. Wright claimed that Delano had been verbally harassing him, and that he then felt compelled to defend himself. Delano did not sustain serious injuries; Wright's defense was weakened by witness testimony that after the assault, he claimed credit for it, and stated that he would have continued if passers-by had not intervened. Wright was sentenced to 30 days in jail and fined $1,000. On April 8, 1880 President Rutherford B. Hayes pardoned Wright, with his release from custody conditional upon payment of the fine.  On December 3, 1889 Delano was elected President of the National Wool Growers Association, a lobbying group organized to advocate for tariff protection of the national wool industry. The association had been formed in 1865, and became more active in the 1880s as a response to the decline in domestic wool production; wool growers faced increasing overseas competition, and had gone from 50 million sheep producing wool in 1883 to 40 million in 1888.

Question:
Robert Larimore Riggs (February 25, 1918 - October 25, 1995) was an American tennis champion who was the World No. 1 or the World co-No. 1 player for three years, first as an amateur in 1939, then as a professional in 1946 and 1947. He played his first professional tennis match on December 26, 1941. As a 21-year-old amateur in 1939, Riggs won Wimbledon, the U.S. National Championships (now U.S. Open), and was runner-up at the French Championships. He was U.S. champion again in 1941, after a runner-up finish the year before.
Small in stature, he lacked the overall power of his larger competitors such as Don Budge and Kramer but made up for it with brains, ball control, and speed. A master court strategist and tactician, he worked his opponent out of position and scored points with the game's best drop shot and lob as well as punishing ground strokes that let him come to the net for put-away shots. Kramer, one of the very few players who was undeniably better than Riggs, writes that there is a major "misconception" about Riggs. "He didn't play some rinky-dink Harold Solomon style, pitty-pattying the ball around on dirt. He didn't have the big serve, but he made up for it with some sneaky first serves and as fine a second serve as I had seen at that time. When you talk about depth and accuracy both, Riggs' second serve ranks with the other three best that I ever saw: von Cramm's, Gonzales's, and Newcombe's." In his autobiography, Riggs wrote, "In the 1946 match with Budge [for the United States Pro Championship], I charged the net at every opportunity. Employing what I called my secret weapon, a hard first serve, I attacked constantly during my 6-3, 6-1, 6-1 victory."  "Riggs," said Kramer, "was a great champion. He beat Segura. He beat Budge when Don was just a little bit past his peak. On a long tour, as up and down as Vines was, I'm not so sure that Riggs wouldn't have played Elly very close. I'm sure he would have beaten Gonzales -- Bobby was too quick, he had too much control for Pancho -- and Laver and Rosewall and Hoad."  Kramer went on to say that Riggs "could keep the ball in play, and he could find ways to control the bigger, more powerful opponent. He could pin you back by hitting long, down the lines, and then he'd run you ragged with chips and drop shots. He was outstanding with a volley from either side, and he could lob as well as any man.... he could also lob on the run. He could disguise it, and he could hit winning overheads. They weren't powerful, but they were always on target."
