NATURE: Jack-of-all-trades - John Leonard Riddell's legacy still blooms in Ohio botany

One of early America’s larger-than-life characters was John Leonard Riddell. Born on Feb. 20, 1807, in Massachusetts, Riddell would burn the candle at both ends for much of his short life.

A wanderlust to explore and expand his horizons sent him westward early on. Riddell landed at Marietta College by 1832, and following studies there, he moved north to Worthington, where he began earning a medical degree at the Ohio Reformed Medical College (closed in 1840). He finished his M.D. at the former Cincinnati College in 1836.

Riddell became far more than a doctor of medicine. Imbued with a quirky, sometimes challenging personality, he nonetheless was adept at diplomacy when need be, and skilled at making connections. The definition of a multipotentialite, Riddell pursued many passions.

Over his career, Riddell became a botanist, medical doctor, chemist, inventor, numismatist (he directed the New Orleans Mint), geologist, politician and author. His sole book is titled “Orrin Lindsay’s Plan of Aerial Navigation with a Narrative of His Explorations in the Higher Reaches of the Atmosphere, and His Wonderful Voyage Round the Moon!” While wordy of title, the book — published in 1847 — foreshadowed space travel.

At his peak, Riddell juggled an appointment to a high federal post, active lab research, a consultancy to the City of New Orleans, involvement in Democratic Party politics, travel and hobnobbing with U.S. presidents, and lucrative real estate investments.

That wasn’t all. Riddell also balanced a wife and eight children while simultaneously managing a mistress and two other kids.

On Oct. 5, 1865, Riddell, who had been elected Louisiana’s governor — his election would be later overturned — delivered a fiery speech against Louisiana’s secession. This diatribe was met with much ill will. Three days later, John Leonard Riddell died of a stroke at 58.

Riddell’s most famous legacy is said to be his invention of the compound microscope. He was also a bacteriologist. However, botanists would disagree. His contributions to our understanding of flora in the fledgling United States cannot be understated.

In 1835, Riddell published “A Synopsis of the Flora of the Western States,” which encompassed an area including Ohio and adjacent states. He had not let the grass grow under his feet during his short Ohio stay, from 1832 to 1836. His publication listed 1,802 plant species.

Then, Ohio and vicinity was still a botanical frontier. As noted by Riddell, “There are large tracts … whose vegetable products have not yet been examined …”

The indefatigable Riddell discovered four plants new to science in Ohio. One of them is the beautiful sky-blue aster (Symphyotrichum oolentangiense). Its scientific epithet denotes the Olentangy River, upon whose banks the botanist discovered the aster in 1832 near Worthington.

One big river to the west, Riddell made another remarkable find in 1834. He encountered an early blooming lily on limestone cliffs along the Scioto River in Dublin. It was named snow trillium (Trillium nivale), and small populations persist in the area to this day.

While scouring a prairie “two miles south of Columbus” in 1834, Riddell met with a statuesque goldenrod quite unlike any other. He dubbed it Ohio goldenrod (Solidago ohioensis). While our namesake goldenrod still occurs in the state, Riddell’s original site has long been obliterated.

That same year, 1834, Riddell trekked to the famous Huffman Prairie near Dayton, where Orville and Wilbur Wright started the nation’s first flying school. There, he found another unknown goldenrod, the eponymous Riddell’s goldenrod (Solidago riddellii). The plant still grows there.

On Sept. 23, I traveled to Kinnikinnick Fen in Ross County, and was delighted to encounter both goldenrods growing side by side. For botanists, Riddell’s legacy lives large, even 157 years after his death.
