Sack Company No. 1 was organized in Janesville as fire police, composed of business men.

The evidence

• “As an auxiliary to the fire department Sack Company No. 1 was organized in March, 1855. This was composed of twenty business men of the city, who gave their services voluntarily to do general police duty during fires. This company has been in existence ever since its organization in 1855 to the present time, though the name was changed to the Janesville Fire Police in 1889. The most prominent business men of the city have been connected with this organization, and it has come to be the pride of the department.”
