Park Street runs parallel with Audley Street. Formerly known as Hyde Park Street, it was one of the later developments of this part of the town, although it was formed anterior to 1768, in which year the actress Nelly O’Brien is stated to have died in it. A very different person also lived here (in No. 113) at a later day, in the person of that Lydia White, who, till the end of her life, delighted to gather around her the lions of the day. One of the last of these to visit her was Scott, who records in his diary that, on November 13th, 1826, he “found her extended on a couch, frightfully swelled, unable to stir, rouged, jesting, and dying.” Harness, writing to Dyce, at an earlier period, tells an anecdote illustrating her readiness of repartee:--“At one of Miss Lydia White’s small and most agreeable dinners in Park Street, the company (most of them, except the hostess, being Whigs) were discussing in rather a querulous strain the desperate prospects of their party. ‘Yes,’ said Sydney Smith, ‘we are in a most deplorable condition; we must do something to help ourselves; I think we had better sacrifice a Tory virgin.’ This was pointedly addressed to Lydia White, who, at once catching and applying the allusion to Iphigenia, answered, ‘I believe there is nothing the Whigs would not do to raise the wind.’” This “really clever creature,” as Sir Walter calls her, died at her house here in 1827. Sir Humphrey Davy also came to live here, from Grosvenor Street, in 1825, and remained a resident till his death, two years after that of Miss Lydia; and Richard Ford, who made a guide-book to Spain, a permanent work of literary charm, was another of the street’s past notable inhabitants. [Sidenote: GREEN STREET.] A few steps southward will bring us to Green Street, in which stands Hampden House, now the residence of the Duke of Abercorn. No. 56 Green Street was formerly known as the “bow-window house,” and here Miss Farren, who afterwards became Countess of Derby, once resided, and gave those suppers to “all the pleasantest people in London,” which Hume, Walpole, and Lord Berwick have recorded. Sydney Smith died in Green Street, at Miss Farren’s old house, in 1845, and here it was that he once told his doctor that he felt so feeble that if anyone were to put a pin into his hand he would not have strength enough to stick it into a Dissenter! [Sidenote: NORFOLK STREET.] Between Green Street and Park Lane intervenes the little Norfolk Street, at a house in which Lord William Russell was barbarously done to death by his valet in 1840. Here Lady Hesketh, the friend of Cowper; Sir James Mackintosh; and, later, Lord Overstone, the millionaire banker, resided. [Sidenote: UPPER BROOK STREET.]
