Thomas Lord (1755-1832) was a Yorkshire-born wine merchant turned cricket entrepreneur who had founded his first ground at Dorset Square in 1787 under the patronage of the Earl of Winchilsea and the Duke of Richmond. The lease on that ground expired in 1810 and Lord moved his operations a short distance to a second ground in north Marylebone, which opened in 1811. The Middle Ground proved no more permanent: Parliament's 1812 act for the construction of the Regent's Canal sliced through the outfield, and by 1813 Lord knew he would have to move again. Colonel Henry Samuel Eyre of the Eyre family estate offered Lord a leasehold on a plot of land at St John's Wood, then a semi-rural area on the northern edge of London. The site had been a duck pond on land that sloped from north-west to south-east — the famous slope of Lord's, dropping about eight feet across the playing area, dates from the original topography. Lord had the turf of the Middle Ground dug up and re-laid on the new site over the winter of 1813-14, a piece of sentimentalism that became part of the ground's mythology. A wooden pavilion was put up by the spring of 1814 and the Lord's Tavern, an extension of the original Dorset Square hostelry, was opened nearby. The ground was ready for play by May 1814; the formal opening came with the MCC v Hertfordshire fixture on 22 June 1814.
