He is believed to be the first man to plow land in Iowa ... sixty acres for his brother Lucius in Couler Hollow north of town. (2) His purchase of two mineral lots, one in 1834 and another in 1835, also proved profitable.
In 1836 Langworthy entered into a partnership with Orrin SMITH. Profits from MINING were invested in the steamer "Brazil," built in 1837 and believed to be one of the first to enter the Upper Mississippi. Unfortunately this boat made very few successful trips between Dubuque and Cincinnati before it crashed into a rock and sank, a totally uninsured wreck. (3)
By 1854 Lucius Hart LANGWORTHY, James LANGWORTHY, Edward LANGWORTHY, and Solon owned one-twelfth of all the real estate in Dubuque. (4) They did a large banking business in Dubuque in 1855 under the name of J. L. LANGWORTHY & BROS. The firm offered to enter land for anyone in the Dubuque, Decorah, Brownsville and Winona land offices on time. They also received deposits and sold exchange on the East. (5) In 1864 the brothers divided 120 acres purchased in 1830 for $500. The tract extended from Tenth to Eighteenth streets and from Iowa to the river. (6) This partnership continued until their retirements in 1862.
The Langworthy estate once reached from present day Third Street to Delhi and from Dodge beyond University Avenue. Upon this land stood four mansion houses arranged in an "L" pattern. James Langworthy's home was at the corner of present-day James Street and Langworthy Avenue, to Lucius Langworthy's home at Hill and Langworthy, Edward Langworthy's (OCTAGON STYLE ARCHITECTURE) at the corner of Alpine and West Third. Solon's home was a short distance south of Edward's on Alpine. (7)
Solon was the only brother never to hold public office. He was, however, the only Langworthy to have a town named in his honor--Solon, Iowa. (8)
