British agriculturalist, 1674-1741; he was among the first to promote modern farming methods in Britain, including the use the of the iron plow. Around the turn of the century, he invented a horse-drawn automatic seed drill with an iron plow (the fore-runner of the improved cast-iron plow, invented in the 1790's), which furrowed the fields and deposited the seeds in linear rows to an acceptable depth, where they would not be picked off by birds and beasts and still have enough soil to grow well. This automation, accompanied by the beginnings of wide-spread use of fertilizer and crop rotation, significantly reduced the amount of seed and labour necessary, allowed weeding around the linear furrows, and increased England's crop yield, paving the way for the population growth and later projects of the industrial revolution.

To my knowledge, Ian Anderson chose the name because it sounded cool, without any particular reference to Mr. Tull's historical importance.
