Robert J. Walker

 
Scientist: John Ernest Walker

British molecular biologist (1941–)

Walker was educated at Oxford University, gaining his DPhil in 1969. In 1974 he joined the staff of the Medical Research Council at the Molecular Biology Laboratory, Cambridge.

In the 1970s Paul Boyer had proposed a theoretical model by which the enzyme ATP-synthase operating in mitochondria could catalyze the production of the adenosine triphosphate molecule (ATP), the main source of cellular energy. The model was partially verified by Walker in 1994. He determined the structure of the enzyme, first by low-resolution electron microscopy and eventually, using x-ray crystallography, constructed a three-dimensional model of the enzyme.

For his contribution to this field Walker shared the 1997 Nobel Prize for chemistry with Paul Boyer and Jens Skou.

Biography: Robert John Walker

Robert John Walker (1801-1869) was a U.S. Senator and served as secretary of the Treasury. A lifelongregular Democrat, he fell out with the party leaders over the status of slavery in Kansas.

Robert John Walker was born in Northumberland, Pa., on July 19, 1801, the son of Jonathan Hoge Walker. After graduating from the University of Pennsylvania in 1819, Robert practiced law in Pittsburgh. He married Mary Bache (Benjamin Franklin's grand daughter) in 1825 and moved to Natchez, Miss., to enter his brother's law office. There he prospered as a lawyer and land speculator, acquiring several plantations. In 1836 he entered the Senate as a Jacksonian Democrat. In spite of his slight stature (he was five feet three inches tall and weighed 100 pounds) and his wheezy voice, he was an active and influential speaker. A party regular, he supported the independent treasury system and constantly attacked the protective tariff, the distribution of the surplus, and abolitionists. As a passionate exponent of manifest destiny, he endorsed the annexation of Texas.

It was largely due to Walker's efforts that the Democrats nominated James K. Polk as their presidential candidate in 1844 instead of Martin Van Buren. Polk appointed Walker to his Cabinet as the secretary of the Treasury. In that office Walker sought to secure the adoption of the independent treasury and to implement tariff reductions. His recommendations were largely responsible for the creation of a Department of the Interior in 1849 and the establishment of customs warehouses. He was an extremely able treasury administrator, and his important financial connections enabled him to negotiate loans for the Federal government on favorable terms during the Mexican War.

After Walker left office in 1849, he settled in Washington, D.C., having disposed of his plantations and slaves in Mississippi in 1843. He practiced law before the Supreme Court and promoted the stocks of railroads in which he was interested. In 1857 President James Buchanan appointed him governor of the territory of Kansas. Although Walker held moderate views on slavery, his stand that the citizens of Kansas should be left free to choose to have slavery or not was regarded as a betrayal by Democratic party leaders, who were committed to make Kansas a slave state. When Buchanan refused to approve the free-soil constitution, Walker resigned. During the Civil War, Walker was active in support of the Union cause and went on a successful mission to Europe to sell Federal bonds in 1863-1864. He died on Nov. 11, 1869, in Washington, D.C.

Walker, Robert John, 1801-69, American public official, b. Northumberland, Pa. A lawyer, he practiced for a time in Pittsburgh. In 1826 he moved to Natchez, Miss. As a Democratic Senator (1836-45) from Mississippi, Walker was an ardent advocate of U.S. expansion and became a leader in the drive to annex Texas. James K. Polk made him Secretary of the Treasury (1845-49), and he had an influential voice in government policies. He reestablished the independent treasury system and helped to improve Anglo-American relations (strained by the Oregon dispute) by the Walker Tariff of 1846, a moderate protective tariff that lowered the rates on many items. His financial administration (he was a firm hard-money advocate) is generally considered one of the most able in the history of the Treasury. In Mar., 1857, he reluctantly accepted appointment as governor of Kansas. Walker was committed to Stephen A. Douglas's popular sovereignty theory, and believed that the majority of Kansans favored admission to the Union as a free state. When President Buchanan refused to support Walker's contention that the proslavery Lecompton Constitution (see under Lecompton) was fraudulently adopted and should be put to popular vote, he resigned (Dec., 1857). He subsequently supported the Union in the Civil War and served as a financial agent in Europe. An expansionist to the end, he had a part in the purchase of Alaska.

Robert John Walker (July 23, 1801November 11, 1869) was an American economist and statesman.

Contents

Early life and education

Born in Northumberland, Pennsylvania, the son of a judge, he graduated in 1819 at the top of his class at the University of Pennsylvania where he was a member of the Philomathean Society, and was admitted to the bar in Pittsburgh in 1821. He practiced law in Pittsburgh from 1822 until 1826 when he moved to Mississippi. There he joined his brother, Duncan Walker, in a lucrative law practice. Walker became a speculator in cotton, land and slaves. (In 1838 he freed his own slaves due to immense pressure from Congress.)

Political life

He became politically prominent during the nullification crisis, and from 1836 to 1845 he sat in the United States Senate as a Unionist Democrat. Being an ardent expansionist, he voted for the recognition of the Republic of Texas in 1837 and for the joint annexation resolution of 1845, and advocated the nomination and election of James K. Polk in 1844. He favored the award of public lands to new states; endorsed a low tariff; opposed distribution of the federal surplus funds for fear of creating an excuse to raise tariff rates; and, significantly, supported the independent Treasury system idea. He also opposed the Bank of the United States.

As a Mississippi senator, Walker was a passionate defender of slavery, both for economic benefits, and because he believed Negroes would fall into turpitude or insanity without firm masters. He claimed that independent Texas had to be annexed to prevent it from falling into the hands of Great Britain, which would use it to spread subversion throughout the South. He warned northerners that if Britain succeeded in undermining slavery, the freedmen would go north, where "the poor-house and the jail, the asylums of the deaf and dumb, the blind, the idiot and insane, would be filled to overflowing."[1]

He was U.S. Secretary of the Treasury throughout the Polk administration, from March 8, 1845 until March 5, 1849, and was generally recognized as the most influential member of the President's Cabinet.

As Treasury Secretary, Walker financed the Mexican-American War and drafted the 1849 bill to establish the United States Department of the Interior. He also supported the independent Treasury system, pushed for a tariff for revenue, and established a warehousing system for handling imports that has had lasting influence.

Walker's greatest work was the preparation of the famous Treasury report of December 3, 1845. It is regarded as the most powerful attack upon the protection system that has ever been made in an American state paper. The Walker Tariff of 1846 was based upon the principles of this paper and was in fact largely the secretary's own work.

After leaving Treasury in 1849, Walker devoted himself to business and land speculation, as well as mining interests.

Walker at first opposed the Compromise of 1850, but was won over later by the arguments of Stephen A. Douglas. He was appointed governor of Kansas Territory in the spring of 1857 by President James Buchanan, but resigned within the year because of his opposition to the Lecompton Constitution. In a resignation letter to Secretary of State Lewis Cass dated December 15, 1857 , he cited clear voting fraud and improper political pressure from the Administration. He did not, however, break with his party immediately, and favored the so-called English Bill. It was partly due to his influence that a sufficient number of anti-Lecompton Democrats were induced to vote for that measure to secure its passage.

He supported the Union cause during the American Civil War and in 1863 and 1864, as financial agent of the United States, did much to create confidence in Europe in the financial resources of the United States. During this time Walker was instrumental in securing a loan of $250,000,000 from Germany.

He practiced law in Washington, D.C., from 1864 until his death there in 1869. Both during and after the Civil War he was a contributor to the Continental Monthly, which for a short time he also, with James R. Gilmore, conducted.

Walker was the father-in-law of Benjamin H. Brewster, Attorney General under Chester A. Arthur.

Initially, Walker County, Texas, was named in his honor. However, due to his support of the Union during the Civil War, the Texas Legislature withdrew the honor and honored Samuel Walker, a Texas Ranger, instead.

Commemoration

The survey ship Robert J. Walker, which served in the United States Coast Survey from 1848 to 1860, was named for Walker.
