I’m Still Here: Saving The Work Of Robert Cornelius

All within a stone’s throw on the dirt and cobblestone streets of 19th century Philadelphia, a hotbed of art, science, and photography held sway. One enterprising young man, Robert Cornelius, a revered portrait photographer, was caught up in the ferment. In 1839, Cornelius, a metallurgist and amateur chemist, took a picture of himself in the yard behind his family’s gas lighting business at 710 Chestnut Street. It is the oldest photographic portrait of a human and the first self portrait ever taken with a makeshift camera. One Philadelphia conservator, Rachel Wetzel, is on the hunt to find and preserve what remains of the groundbreaking photographer’s brief career.

A series of his busy portrait studios ran along the diagonal constellation of art and science institutions of the day around 8th and Market Streets. Lodge Alley, now Ranstead Street, was where Cornelius set up the first photographic studio in the city, the second one of its kind in the country. The Victorian photographer was on the cusp of Philadelphia’s booming photography industry, ushering in the daguerrotype era of the 1840’s. Captivated by the new medium, Cornelius adapted his technical background to churn out scores of fine photographic portraits, some 54 of which are known to still exist today. It was the fashion for business leaders to sit still for “R. Cornelius” and to have themselves recorded for posterity. Cornelius also prepared silver coated copper plates for Joseph Saxton who took a daguerreotype of Central High School, the oldest surviving photograph in America.

“Cornelius partnered with Paul Beck Goddard, a chemist at Penn, and together the two discovered the use of bromine as a sensitizer that helped accelerate exposure times,” said Rachel Wetzel, photograph conservator for Conservation Center for Art & Historic Artifacts. “Cornelius had a chemistry background as well, so he would have had a grasp on how halogens work. The discovery is attributed to Goddard, but it was well known the two worked together and it was a clear partnership.”

Drawing from examining historic records, Wetzel suspects that the two were trying to solve a problem in secret for their own gain, giving the process a more commercially functional purpose. They kept this information close. Eventually it was leaked and other daguerreotypists began sensitizing their plates with bromine and iodine, opening up the possibility for more numerous and viable photographic portrait studios in Philadelphia.

“My field is pretty tiny,” said Wetzel. By her estimation, there may be less than 200 conservators like herself in the entire world. She came to the work by way of pharmacy school, chemistry, art history, and paper and object conservation. Her painstaking craft takes a certain quirky mindset. “When I was a child I remember lining up tiny plastic toy figures in a row and it had to be just so,” she said.

Wetzel, whose self-described messy work area, is actually tidy enough for a small library of books and reference materials, tools, a desktop computer, and portable unit for photographing small daguerrotypes on her quest to find newly-attributable Cornelius photographs.

Some early photographic conservation methods innocently rendered more harm than good. The Hippocratic Oath for conservators now could be posited as “Above all, do nothing that is not reversible.”

“I do everything by hand with real materials. All the media we use are soluble with a chemical,” Wetzel said, who conducts studies on new conservation techniques for the fugitive, silvery tracings of vintage daguerrotypes. She sometimes initiates research out of pocket. Wetzel is resigned to the dearth of grant money available for the specialized, arcane pursuits of a photograph conservator. Yet these professionals are the vanguard, reeling in the fading and ephemeral evidence of what and whom came before us.

“I want these to last for many generations from now. Children today have no idea of [analog] cameras and film,” she said. “Even the tactile experience of holding a beautiful photographic print is foreign to them.” She adds, “The way we talk about photography today has to be erased for us to understand the daguerrotype period.”

Cornelius was an innovator at the intersection of art and science, driven by the desire to bring photography to the forefront. The new medium caught on quickly in Philadelphia for commercial use, but it was still years away from being a reliably profitable venture. After Cornelius opened his studio on Ranstad Street in 1841, he abandoned photography three years later, presumably broke and frustrated, and went back to working for his family’s lamp-making business. The father of the world’s first “selfie” died in 1893 and now rests in Section J, Lot 63 at Laurel Hill Cemetery.

  1. Davis says:

    A great piece – glad he is being further studied. The family’s gas fixtures were also notable and many survive.

  2. Tim Plummer says:

    Very impressive piece! Philadelphia is lucky to have you!
    Tim ?

  3. Roberto Pace says:

    Very cool – thank you!

  4. Martin Kelley says:

    Very cool. I see his office/house has been given a new facade and is renting. I’ve half a mind to ask for a showing in which I could casually ask if the courtyard in back was a shared space. I posted my Google wormhole on the locale a couple of years ago

  5. Ron Avery says:

    I had always thought the first daguerreotype taken in America was also done in Philly. It was also taken in 1839 of Central High School near 13th and Market by Joseph Saxton, a chemist at the nearby U.S. Mint.

    1. Cavin Clayton says:

      My mother is a Cornelius and she has traced the Cornelius family name and discovered many locations in Europe. I believe including Sweden. She has also informed me the Cornelius name can be traced to Roman society.

  6. Michael cornelius says:

    Im trying to find out any real information on the cornelius family members around north eastern United States. I live in Michigan and have not found out much about my family history. Only dead ends and mysterious men and not a thing about where we come from in Europe. We are all immigrants here in the United States.

    1. Joseph G. Brin says:


      Rachel Wetzel, photograph conservator for Conservation Center for Art & Historic Artifacts, has been in touch with at least one member of the Cornelius family.

  7. Kurt Peterson says:

    Im curious as to why the city labels his former business as ranstead st. And this article says chestnut st.

  8. Joe Brin says:

    The article indicates that his family’s gas lighting business was at 710 Chestnut Street…

    His photography studio, I believe, would have been on Lodge Alley, now Ranstead Street, runs parallel to Chestnut.

    Thank you for your interest.

  9. Shawn Harbert says:

    I’m trying to find out my family history. I came across a picture of my great, great,great, grandfather. On the picture it says.
    The Cornelius studios,
    316market st
    Lewisburg Pa.
    His last name was Chappell. If anyone could help, I would be so grateful.

  10. Robert Roy Cornelius Jr says:

    My daddy’s name is Robert Cornelius senior I am Robert Corey communist Jr passed away 2012

  11. Rebecca Murray says:

    My name is Rebecca Murray, I have a photo from Cornelius it looks to be in the 1800’s any ideas I would like to know the history
