Krišjānis Ķergalvis, a key figure in Latvia's construction history, was born in a poor family and rose to prominence by mastering the trade of masonry. In the late 19th century, he earned the title of master mason and founded his own construction company, leading to the successful completion of numerous significant architectural projects in Riga and beyond. Among his notable constructions are several iconic buildings, including those that now house important state institutions.

During the late 1800s, Ķergalvis partnered with fellow builder Pēteris Radziņš to establish one of Latvia's largest brick manufacturing plants near Kalnciems. To facilitate the transportation of bricks to Riga, they acquired a steamboat named 'Delfīns'. This move not only boosted their construction endeavors but also contributed to the growing urban landscape of Riga, as they completed projects such as the Riga City Theater, which is now known as the Latvian National Theater.

Ķergalvis' legacy extends beyond his wealth; he played a crucial role in shaping Latvia's architectural heritage and industrial capacity during a transformative period in the country's history. His story is a testament to how individuals from modest beginnings can contribute significantly to their communities and nations, marking the broader narrative of economic development in Latvia in the late 19th century.
