Task: Question Answering
Input (English): Passage: Wheeler had been expecting and openly hoping for war with Nazi Germany for a year prior to the outbreak of hostilities; he believed that the United Kingdom's involvement in the conflict would remedy the shame that he thought had been brought upon the country by its signing of the Munich Agreement in September 1938. Volunteering for the armed services, he was assigned to assemble the 48th Light Anti-Aircraft Battery at Enfield, where he set about recruiting volunteers, including his son Michael. As the 48th swelled in size, it was converted into the 42nd Mobile Light Anti-Aircraft Regiment in the Royal Artillery, which consisted of four batteries and was led by Wheeler – now promoted to the rank of colonel – as Commanding Officer. Given the nickname of "Flash Alf" by those serving under him, he was recognised by colleagues as a ruthless disciplinarian and was blamed by many for the death of one of his soldiers from influenza during training. Having been appointed secretary of the Society of Antiquaries in 1939 and then director in 1940, he travelled to London to deal with society affairs on various occasions. In 1941 Wheeler was awarded a Fellowship of the British Academy. Cole had meanwhile entered into an affair with a man named Clive Entwistle, who lambasted Wheeler as "that whiskered baboon". When Wheeler discovered Entwistle in bed with his wife, he initiated divorce proceedings that were finalised in March 1942.In the summer of 1941, Wheeler and three of his batteries were assigned to fight against German and Italian forces in the North African Campaign. In September, they set sail from Glasgow aboard the RMS Empress of Russia; because the Mediterranean was controlled largely by enemy naval forces, they were forced to travel via the Cape of Good Hope, before taking shore leave in Durban. There, Wheeler visited the local kraals to compare them with the settlements of Iron Age Britain. The ship docked in Aden, where Wheeler and his men again took shore leave. They soon reached the British-controlled Suez, where they disembarked and were stationed on the shores of the Great Bitter Lake. There, Wheeler took a brief leave of absence to travel to Jerusalem, where he visited Petrie on his hospital deathbed. Back in Egypt, he gained permission to fly as a front gunner in a Wellington bomber on a bombing raid against Axis forces, to better understand what it was like for aircrew to be fired on by an anti-aircraft battery. 
Question: What is the last name of the person who was appointed secretary of the Society of Antiquaries in 1939?
