Not to be a complete History wonk or anything BUT Jethro Tull IS a Guy, AND a Band. Just read this entry from Britannia...
"Jethro Tull
(1674-1741)
Born: 1674 at Basilson, Berkshire
Agriculturalist
Died: 1741 at Hungerford, Berkshire
Jethro Tull (1674-1741), born in Basildon in 1674, was a major pioneer in the modernisation of agriculture. The son of a Berkshire farmer, he trained for a legal career, but financial problems compelled him to opt instead for farming. Determined to improve agricultural methods and increase yields, Tull experimented at Howberry farm, Crowmarsh, near Wallingford with a seed-drill which could sew three rows of seeds simultaneously. Later, he devised a horse-drawn hoe to clear away weeds. In 1731, Tull published his ideas about farming and plant nutrition in The New Horse Houghing Husbandry: or, an Essay on the Principles of Tillage and Vegetation'. Despite initial resistance to Tull's revolutionary ideas, they were eventually adopted by large landowners, and in time formed the basis of modern agriculture. Tull died at Prosperous Farm, near Hungerford on 21 February 1741. "

and then there is Jethro Tull the band... from allmusic.com...
"Jethro Tull was a unique phenomenon in popular music history. Their mix of hard rock; folk melodies; blues licks; surreal, impossibly dense lyrics; and overall profundity defied easy analysis, but that didn't dissuade fans from giving them 11 gold and five platinum albums. At the same time, critics rarely took them seriously, and they were off the cutting edge of popular music since the end of the 1970s. But no record store in the country would want to be without multiple copies of each of their most popular albums (Benefit, Aqualung, Thick as a Brick, Living in the Past), or their various best-of compilations, and few would knowingly ignore their newest releases. Of their contemporaries, only Yes could claim a similar degree of success, and Yes endured several major shifts in sound and membership in reaching the 1990s, while Tull remained remarkably stable over the same period. As co-founded and led by wildman-flautist-guitarist-singer-songwriter Ian Anderson, the group carved a place all its own in popular music.
Tull had its roots in the British blues boom of the late '60s. Anderson (b. Aug. 10, 1947, Edinburgh, Scotland) had moved to Blackpool when he was 12. His first band was called the Blades, named after James Bond's club, with Michael Stephens on guitar, Jeffrey Hammond-Hammond (b. July 30, 1946) on bass and John Evans (b. Mar. 28, 1948) on drums, playing a mix of jazzy blues and soulful dance music on the northern club circuit. In 1965, they changed their name to the John Evan Band (Evan having dropped the "s" in his name at Hammond's suggestion) and later the John Evan Smash. By the end of 1967, Glenn Cornick (b. Apr. 24, 1947, Barrow-in-Furness, Cumbria, England) had replaced Hammond-Hammond on bass. The group moved to Luton in order to be closer to London, the center of the British blues boom, and the band began to fall apart, when Anderson and Cornick met guitarist/singer Mick Abrahams (b. Apr. 7, 1943, Luton, Bedfordshire, England) and drummer Clive Bunker (b. Dec. 12, 1946), who had previously played together in the Toggery Five and were now members of a local blues band called McGregor's Engine.
In December of 1967, the four of them agreed to form a new group. They began playing two shows a week, trying out different names, including Navy Blue and Bag of Blues. One of the names that they used, Jethro Tull, borrowed from an 18th-century farmer/inventor, proved popular and memorable, and it stuck. In January of 1968, they cut a rather derivative pop-folk single called "Sunshine Day," released by MGM Records (under the misprinted name Jethro Toe) the following month. The single went nowhere, but the group managed to land a residency at the Marquee Club in London, where they became very popular."
Sorry top be such a know-it-all jerk here... But as a European History Teacher I've always taught Jethro the man to introduce the Agricultural Revolution in England in the early 1700's that freed up the workforce necessary for the new Industrial Revolution gaining momentum in the midlands of England... Then I play them Aqualung at full blast...
