Endres Mfg. Co. finds itself in a rare field, a family business, entering its fourth generation. Statistics show that only about 3% of family businesses ever reach that level. This is a look back at how Endres Mfg. got to this point.Lawrence M. Endres Sr. was born in 1884 and raised in Martinsville, Wisconsin. After beginning his entrepreneurial career with several patents and a small business with his brothers, he branched out on his own and founded L.M. Endres Manufacturing Company in 1926 at 305 West Street in Waunakee. He found early success with his many inventions, including sixteen patents. Some of his more popular inventions were his folding drawbar and his disc sharpener. In 1930 the business was incorporated and the name changed to Endres Mfg. Co.

Larry Jr. was born in 1924 and started his tenure at Endres Mfg. when he was only six. In 1938 Larry bought the company’s first Sears & Roebuck welder for $96. Larry invented his own variation of the folding drawbar in 1940 and attempted to patent it, but was too young. Due to World War II Larry enlisted in the service in 1943 and was forced to close the doors of the company. When he returned, though, he got right back to work. He invested in a truck and started fabricating steel beams for the residential market. This was the beginning of the structural steel business which today makes up over 95 percent of company sales. Larry also began the pier business when a friend asked him to build him one. It was an opportunity to keep employees working during the winter months. Although the shoreline business is only about 2 percent of sales today, it provides company exposure to the non-construction community.

Larry married Leona Wallin in June 1950 after Lee had completed nursing school, and they lived with Larry’s parents until 1953 when their first child, Diane, was born. Lawrence Sr. was in late stages of Parkinson’s disease by this time, and he died in November of that same year. When Lee and Larry’s son Ronald was born in 1957, Lee gave up her nursing career and became the first full-time bookkeeper at Endres.

One of Endres Mfg. Company’s biggest jobs during this time was for Madison Gas & Electric. Endres employees welded most of the original natural gas lines for Waunakee and many neighboring communities.
