[4] In 1907, Paul P. Wentz engraved the Lord's Prayer on a brass pin head with a diameter of 2 mm or .079 inch.
Before commencing the work, Lundberg realized that he needed to be in top physical shape to undergo the rigors of such a long, nerve-racking endeavor.
When he felt himself 'fit' Lundberg started the next stage, which was the manufacture of a special engraving tool, which had to be of a degree of fineness beyond that attempted by the makers of the most minute instruments.
When he finished he had a point so fine that it was hardly visible to the naked eye, and yet had sufficient tensile strength to last through the whole long-drawn, nerve-straining process.
Alvin H. Hankins, a jeweler and lens grinder that knew Lundberg and eventually was his employer in Seattle, was present during most of the engraving.
In the early 1930s he wrote to Ripley's Believe It or Not in response to one of their cartoons (Dec. 16, 1929) that wrongly credited a Mr. Charles Baker with engraving the pin.
He also bound his wrists tightly with leather straps, because the rhythm of his pulse caused the engraving tool to skip.
Lundberg could only work on the pin in the evenings, when the rumbling trolley cars that passed by his shop had stopped running for the day.
Two or three pins Lundberg had started, only to have some unexpected minute jar deflect the needle and spoil the letters that had been drawn.
Starting early one morning on the ninth line Lundberg saw through the microscope the graving tool swerve and cut through the completed part.
But he started out, a few strokes a night, reaching his home early every morning with each individual nerve on edge and with eyes aching from the strain.
"[2] Being exhausted with nervous prostration and in desperate need of total rest, Lundberg entrusted the task of revealing the pin to the public to his brothers Carl and Mauritz.
Along with the pin was a gold needle on the point of which Lundberg had engraved the letters US to honor his adopted country.
[11] In 1919 Lundberg, his wife Anna, and son Edris moved to Seattle, Washington where he was employed by his longtime friend Alvin H. Hankins, who owned a jewelry business.
