A man much maligned by Hollywood!
Navigator: In 1789, during command of HMS Bounty, Bligh and 18 loyal men were set adrift in an overloaded ship's launch. They were supplied with four cutlasses, no firearms, about one weeks supply of food and water, and very basic navigation equipment but no charts or a marine chronometer. A pocket watch was used to regulate time. Bligh and 17 men reached Timor alive, a journey of 3,618 nautical miles (6,700 kms) and thence to Batavia (Dutch East Indies). During this epic journey, only one of his men died, being killed by natives at Tofua.
Disciplinarian: In comparison to his peers, Bligh could be described as sparing in his punishments, scolding when others whipped and whipping when others hanged. An educated man, he was interested in science and knowledgeable that good diet and cleanliness were necessary for crew welfare. He was finicky about the quality of their food and insisted upon the Bounty being kept very clean.
Governorship of New South Wales: His administration provoked the anger of several influential individuals and, more importantly, senior officers of the New South Wales Corps who, in defiance of British government regulations, were engaged in private business for profit, which Bligh was determined to end. Several hundred soldiers of the New South Wales Corps marched on Government House and arrested Bligh following which a rebel government was installed. Subsequently, these actions were declared illegal and mutinous by the British Government.
Personal Courage: At the Battle of Camperdown on 11 October 1797, Bligh engaged three Dutch vessels. While the Dutch suffered serious casualties, only seven of Bligh's crew were wounded. He captured the Dutch flagship and their fleet commander, Vice-Admiral Jan de Winter.
Bligh also served under Admiral Nelson at the Battle of Copenhagen on 2 April 1801. He was praised by none less than Nelson for his contribution to the victory.
Edit 1: I believe the former Queensland Premier, Anna Bligh, is related.
Edit 2: Another individual maligned on film ("Zulu") was Private Henry Hook VC, portrayed as a waster fond of the drink. In life, he was teetotal and had been awarded good-conduct pay just prior the battle.
