Brother Rutherford and the Spanish FLu

Those who have read the history of Watchtower are aware that from 1919 until his death in 1942 he suffered from illness. Although it is not confirmed he contacted the Spanish Flu while in the federal prison in Atlanta, in the book "Faith on the March" Macmillian says this.

"The flu came along and our Sunday school was discontinued for a time. But just before we left all the classes were united in honor of our leaving. We were going on Monday, and that Sunday Rutherford talked for about three-quarters of an hour to that group. We had a number of the officers in there and many of the men had tears running down their cheeks. They were deeply impressed. We left a little group in there that was organized to continue their study."
Pg 104-105
"Although Rutherford had been ill in bed all day Monday, he went to the auditorium that night to talk to the 1,500 assembled, but after about an hour he had to give up and an associate completed his lecture.
For several weeks he was in serious condition and we thought he might not survive. Due to his weakened condition he had contracted pneumonia. The doctors said his trouble was due to the poisons in his system from impure air and poor food while in the Atlanta penitentiary."
​Pg 112.

So although we do not know for certain Brother Rutherford contact the Spanish Flu in prison, Macmillan does confirm it entered the prison while they were there and afterwords Rutherford suffered for the rest of his like. Which was only 24 years.
