Input: Question: How many years had David Hamilton been a professional when he designed The Nelson Monument on Glasgow Green? Passage:Nelson became – and remains – Britain's greatest naval war hero, and an inspiration to the Royal Navy, yet his unorthodox tactics were seldom emulated by later generations. The first monument to be erected in Britain to commemorate Nelson may be that raised on Glasgow Green in 1806, albeit possibly preceded by a monument at Taynuilt, near Oban in Scotland dated 1805, both also commemorating the many Scots crew and captains at the battle. The Nelson Monument on Glasgow Green was designed by David Hamilton and paid for by public subscription. Around the base are the names of his major victories: Aboukir (1798), Copenhagen (1801) and Trafalgar (1805). The Nelson Monument overlooking Portsmouth was built in 1807–08 with money subscribed by sailors and marines who served at Trafalgar. In 1808, Nelson's Pillar was erected by leading members of the Anglo-Irish aristocracy in Dublin to commemorate Nelson and his achievements (between 10% and 20% of the sailors at Trafalgar had been from Ireland), and remained until it was destroyed in a bombing by "Old IRA" members in 1966. Nelson's Monument in Edinburgh was built between 1807 and 1815 in the form of an upturned telescope, and in 1853 a time ball was added which still drops at noon GMT to give a time signal to ships in Leith and the Firth of Forth. In summer this coincides with the one o'clock gun being fired. The Britannia Monument in Great Yarmouth was raised by 1819. Nelson's Column, Montreal began public subscriptions soon after news of the victory at Trafalgar arrived; the column was completed in the autumn of 1809 and still stands in Place Jacques Cartier.
