Task: Question Answering
Input (English): Passage: Private Charles H. Kuhl, of L Company, U.S. 26th Infantry Regiment, reported to an aid station of C Company, 1st Medical Battalion, on 2 August 1943. Kuhl, who had been in the U.S. Army for eight months, had been attached to the 1st Infantry Division since 2 June 1943. He was diagnosed with "exhaustion," a diagnosis he had been given three times since the start of the campaign. From the aid station, he was evacuated to a medical company and given sodium amytal. Notes in his medical chart indicated "psychoneurosis anxiety state, moderately severe (soldier has been twice before in hospital within ten days. He can't take it at the front, evidently. He is repeatedly returned.)" Kuhl was transferred from the aid station to the 15th Evacuation Hospital near Nicosia for further evaluation.Patton arrived at the hospital the same day, accompanied by a number of medical officers, as part of his tour of the U.S. II Corps troops. He spoke to some patients in the hospital, commending the physically wounded. He then approached Kuhl, who did not appear to be physically injured. Kuhl was sitting slouched on a stool midway through a tent ward filled with injured soldiers. When Patton asked Kuhl where he was hurt, Kuhl reportedly shrugged and replied that he was "nervous" rather than wounded, adding, "I guess I can't take it." Patton "immediately flared up," slapped Kuhl across the chin with his gloves, then grabbed him by the collar and dragged him to the tent entrance. He shoved him out of the tent with a kick to his backside. Yelling "Don't admit this son of a bitch," Patton demanded that Kuhl be sent back to the front, adding, "You hear me, you gutless bastard? You're going back to the front."Corpsmen picked up Kuhl and brought him to a ward tent, where it was discovered he had a temperature of 102.2 °F (39.0 °C); and was later diagnosed with malarial parasites. Speaking later of the incident, Kuhl noted "at the time it happened, [Patton] was pretty well worn out  ... I think he was suffering a little battle fatigue himself." Kuhl wrote to his parents about the incident, but asked them to "just forget about it." That night, Patton recorded the incident in his diary: "[I met] the only errant coward I have ever seen in this Army. Companies should deal with such men, and if they shirk their duty, they should be tried for cowardice and shot."Patton was accompanied in this visit by Major General John P. Lucas, who saw nothing remarkable about the incident. After the war he wrote:
There are always a certain number of such weaklings in any Army, and I suppose the modern doctor is correct in classifying them as ill and treating them as such. However, the man with malaria doesn't pass his condition on to his comrades as rapidly as does the man with cold feet nor does malaria have the lethal effect that the latter has.
Patton was heard by a war correspondent angrily denying the reality of shell shock, claiming that the condition was "an invention of the Jews.". 
Question: What is the last name of the man that wrote "the man with malaria doesn't pass his condition on to his comrades as rapidly as does the man with cold feet"?
Output (English): Lucas.
