Wilhelm Carl August Thielepape (July 10, 1814 – August 7, 1904), was an architect, engineer, teacher, photographer, and lithographer. He was Mayor of San Antonio, Texas during part of the Reconstruction era, and later an attorney in Chicago, Illinois.
Arrival with Prince Carl of Solms-Braunfels
Thielepape arrived in Texas in 1844, with the first Adelsverein colony accompanying Prince Carl of Solms-Braunfels from Germany. After participating in a tour of the eastern and central United States in 1850, Thielepape settled in Carlshafen (Indianola), Texas as a surveyor.
Uvalde County and Comal County
On May 2, 1855, Reading Wood Black hired Thielepape, to plat and lay out Encina, the town later known as  Uvalde, Texas. For a short time, Thielepape lived in Comal County where he designed the 1860 courthouse.
Thielepape moved to San Antonio in 1854.
On April 2, 1858, he was among the organizers of the San Antonio's  German-English School.
In 1857, Thielepape designed the San Antonio Casino Club on Market Street, which opened in 1858. The club had its beginnings as a social gathering in 1854 in the home of Carl Hummel. When the club was chartered in 1857, its membership consisted of 106 German Texan men. The Market Street location hosted family entertainment, balls, social gatherings, music, activities, lectures and plays. Thielepape was a tenor who also founded the Beethoven Männerchor (men's choir) on February 23, 1867, to preserve German song, music, and language. He conducted the Beethoven Männerchor at the Casino.
Wilhelm Thielepape was among those who raised the Union flag over the Alamo on July 21, 1865, and who also passed out wine and songbooks in celebration of the Union victory. The four-month delay between the end of the Civil War in April and this celebration is not long in light of the 2½ years between the Emancipation Proclamation and the news of it being delivered in Galveston.
Thielepape was appointed Reconstruction Mayor of San Antonio on November 8, 1867. In his tenure as Mayor, Thielepape's administration built bridges, laid macadam streets, and strengthened the public schools. On March 12, 1872, Thielepape was removed from office and succeeded by Francois P. Giraud, but he remained active in the community.
In April 1874, Thielepape turned the Beethoven Männerchor over to Andreas Scheidemantel.
Chicago and later years
Thielepape then moved to Chicago to participate in the building boom that followed the Great Chicago Fire. By 1887, he was an attorney with the Germania Life Insurance Company in Chicago. He died in Chicago on August 7, 1904.
