The Slezak family lived in this house for twenty-two years, from 1869 to 1891. According to public records, the first owner of the house was Joseph Slezak but a preceeding city record book that would likely indicate the earlier owner has been lost.
It is believed the prior owner may have been the brother of Joseph Slezak. According to burial records, John Slezak died in 1869 at the age of 49 years and was not buried in a lot with any other Slezak family member. It is possible, as the sole surviving heir in America of John Slezak, Joseph inherited the house in 1869. Records do not indicate that the house was purchased by Joseph.

Joseph Slezak was born in 1819 and came to America from Bohemia, a region of Czechoslovakia, with his wife Catharine and sons Frank and Joseph. The exact year the Slezak family arrived in America is not known. Joseph was a tailor and his son, Joseph, Jr., was a saddler.
Joseph Krivanec(k) immigrated from Bohemia in 1882 with his wife, Catherina and son, Joseph and bought the Slezak house in 1892. The purchase price was $1,150.* The Krivanek family owned the house for eighty-three years. Their daughter, Marie, was born in 1895 and her descendents (of Marie Michalek) owned the house until 1975.
Work by family members and tenants of the house, some from attached or adjacent buildings no longer standing, included homemaker, tailor, saddler, blacksmith, stonemason, carpenter and fireman. For many of the early years, the house was occupied by two families - one living downstairs and the tenants, upstairs. During these years, access to the second floor residence was from exterior stairs.
Joseph Slezak died in 1890 and his wife Catharine, died in 1901.
Both are buried at Sts. Peter and Paul Cemetery in St. Louis.

For the first time in many years, descendents of Marie Michalek (Krivanek) visited the house in June 2007.

Many Missouri public records, like marriage and death certificates, are now available on-line.
Almost without exception, every structure in Soulard once had window shutters. Louvered window shutters provided maximum ventilation, privacy, and a little security during the warm months in St. Louis. Historically accurate window shutters have been restored to the Slezak House using Timberlane, the finest wooden shutters made.

The window box cages on the Slezak House are from Smith & Hawken.
The liners are handmade by a local craftsman.
Slezak House is preparing to consider solicited purchase offers in June, 2011.
