Throughout his life, he held various roles, including that of a newspaper editor, postmaster, and law school dean, reflecting a diverse and impactful career.

Early life and career

Mark Lindsey De Motte was born on December 28, 1832, in Rockville, Indiana. His early education laid the groundwork for his future pursuits in law and politics. De Motte attended Indiana Asbury University, now known as DePauw University, where he graduated from the literary department in 1853. He continued his studies at the same institution, completing his education in the law department in 1855. Following his graduation, he was admitted to the bar and began practicing law in Valparaiso, Indiana, the same year.

De Motte's legal career began to take shape when he was elected as the prosecuting attorney for the sixty-seventh judicial district in 1856. This role marked the beginning of his public service and involvement in the legal community. His commitment to the law and public service would later be underscored by his military service during the Civil War.

In 1861, De Motte enlisted in the Union Army, where he quickly rose through the ranks. He began his service as a first lieutenant and was promoted to captain in 1862. By 1865, he achieved the rank of colonel, a title that would remain with him for the rest of his life, even after he left military service later that year. His experiences during the Civil War would shape his perspectives and inform his subsequent political career.

After the war, De Motte relocated to Lexington, Missouri, where he resumed his law practice. He also took on the role of editor and proprietor of the Lexington Register, a local newspaper. His engagement in journalism allowed him to influence public opinion and stay connected to the political landscape. Despite his efforts, De Motte faced challenges in his political aspirations, running unsuccessfully for Congress in both 1872 and 1876. He was active in the Republican Party and served as a delegate to the Republican National Convention in 1876, further solidifying his political connections.

In 1877, De Motte returned to Valparaiso, Indiana, where he continued his legal practice. He played a significant role in the establishment of the Northern Indiana Law School in 1879, which would later become the Valparaiso University School of Law. This institution contributed to the education of many future lawyers and reflected De Motte's commitment to legal education and professional development.
