From Beards and Attire - readJW.Info
“Brother Balzereit asked Brother Rutherford for permission to buy a rotary press. Brother Rutherford saw the necessity and agreed, but on one condition. He had noticed that over the years Brother Balzereit had grown a beard very similar to the one that had been worn by Brother Russell. His example soon caught on, for there were others who also wanted to look like Brother Russell. This could give rise to a tendency toward creature worship, and Brother Rutherford wanted to prevent this. So during his next visit, within hearing of all the Bible House family, he told Brother Balzereit that he could buy the rotary press but only on the condition that he shave off his beard. Brother Balzereit sadly agreed and afterward went to the barber. During the next few days there were several cases of mistaken identity and some funny situations because of the “stranger” who was sometimes not recognized by his fellow workers.”
