title: Pearl Brewing Company
context: The site owned and operated by the Pearl Brewing Company was originally known as both the J. B. Behloradsky Brewery (1881–1883) and the City Brewery.[3]  Privately held and poorly run for two years, the City Brewery was purchased by an investment group in 1883.  The investment group was composed of local businessmen and several moguls already involved in brewing at San Antonio's other major brewery, the Lone Star Brewing Company. Together they formed the San Antonio Brewing Company (1883–1888), and began to raise capital to fully restart and improve operations at the brewery.[4]  In 1886, after three years, the company had secured the necessary capital and began full-time operations at the brewery again.  The name San Antonio Brewing Association was used as a parent to the brewing company, since it also managed some of the founding members' other business interests.  Functionally, the business structure worked, but it caused confusion with city officials, customers, and business partners; therefore, in the end, the investment group dissolved the San Antonio Brewing Company and used the San Antonio Brewing Association (1888–1918) name for all operations and business transactions. Thus, in seven years, the same brewery had three different names.[5]  In addition, the name City Brewery was frequently used.  The first logos used for the San Antonio Brewing Company/Association even featured the name City Brewery in the logo. City Brewery was carried over from the Behloradsky days and was used until the beginning of Prohibition in 1918.[5]
