Brantz Mayer

Brantz Mayer was born in Baltimore, Maryland, to Christian Mayer and Anna Katherina Baum Mayer.^[1] Christian Mayer was a German who emigrated in 1784 along with a friend, Lewis Brantz.^[2] The two formed a business partnership that would last for decades, trading as far away as with the East Indies and Mexico.

In 1809, Christian Mayer had a second son (the first was lawyer Charles F. Mayer), whom he named after his friend and business partner. Childless himself, Lewis Brantz would eventually name the younger Mayer as his heir.^[2]

After graduating from St. Mary's Seminary in Baltimore, Brantz Mayer sailed for the East, visiting Java, Sumatra, and China, and returned in 1828. He studied law during this long voyage, and on his return home entered law school and was admitted to the bar in 1829.^[3] He practiced law from 1832 until 1841, when he was appointed secretary of legation to Mexico, where he remained a year, and on his return edited for a short time the Baltimore American newspaper. Brantz Mayer was again secretary of the United States legation to Mexico in 1842^[4] and 1843.^[3]

When he returned home after his 1843 visit, he published his first work, Mexico as it Was, and as it Is (Philadelphia, 1844), which was accused of unfairness and gave rise to animated controversy. In the winter of 1844, Mayer founded the Maryland Historical Society, the original object of which was “the collecting the scattered materials of the early history of the state, and for other collateral purposes.” In 1857, he was elected a member of the American Antiquarian Society.^[5]

During the American Civil War, Mayer was an active Unionist, and in 1861 was appointed president of the Maryland Union State general committee, and did much to aid the Union cause.^[3] In 1867, he was appointed a paymaster in the United States army, a post which he resigned in 1875.^[1] He contributed to the Maryland Historical Society the Journal of Charles Carroll of Carrollton during his Mission to Canada, and Tah-gah-jute, or Logan and Captain Michael Cresap.

On September 27, 1835, Mayer married Mary Griswold, and they had five daughters.^[1] Mayer remarried to Cornelia Poor, they had three daughters together.^[1]

He died on February 23, 1879, at the age of sixty-nine.^[1]
