The once employer of 70,000+ is now known as WHO, and George Eastman's ashes entombed at the entrance to Kodak Park are passed by mere hundreds these days. Legend has it the company died for missing digital photography. Reality is the UofR business School geniuses killed the company to maximize short term profit by bringing in Fisher from Motorola to sell off Kodak company by company. When he had it almost done they swapped him out for a personal friend of BigearsBama who managed to get a hanger to collapse on one of the company planes visiting BigEars for a Superbowl party.
BigBlueX also managed to self destruct, first selling the tower and then Webster and renting back. Then they put in a company built female AA to run the show all the way to hell. She and Perez of Kodak both sat on the clean KneeGro's Job Creation & economic development Council where Ursula Burns created several maid and lawn care jobs for her holdings. Meanwhile Ursula cleaned up by selling out employee stock holders invested in X stock for their retirement. At least it can be said X blew it on their own by completely missing desktop computer printing in spite of inventing Docutec and if memory serves their 820 desktop.
Rochester lost General Railway Signal too, along with Bausch & Lomb, Ritter Dental moved away, Taylor Instrument got swallowed, Stromberg Carlson disappeared and a few hundred suppliers and support shops went away too.
You may also remember Midtown Plaza just north of X Tower. The last roll of retail downtown after Gilbert McCurdy looked at PigeonHole Parking from his office atop his department store and declared downtown is dead in 1960. Well, that too is pretty flat these days thanks to demolition after the idiot mayor of the city bought the complex that cost $50,000 a month to maintain.
He was following on the track record of the Mayor who bought Rochester the famed aluminum hulled fast ferry boat made in Australia that would come to be known as the Edmund FitzJohnson. Being a brilliant Awfreekin-American Johnson who evolved from the world of Social agencies to become Mayor managed to steal a Canadian plan to run ferrys from Rochester to Toronto to alleviate border backups at Niagara Falls. It was brilliant in 2000, and Grady thought he swiped the complete plan. When the Canadians saw what was happening they made sure no Toronto terminal existed as they watched Grady rebuild the old Port of Rochester to happy ferry land and try to figure out how to get rid of the old blast furnace residue long buried. The boat arrived via Seaway where it took only minor damage being squeezed through the locks and arrived at the dock on its sole remaining functioning MAN engine to await repairs. Then those nasty airplanes knocked down the Twin Towers and a whole new world of international travel regulations came into being, while the engines got fixed. The hired crew sat around in their comfortable accommodations and the Fire Department insisted a fireman had to be standing next to the hose as fuel was pumped aboard. When the Edmund finally got running and made a test voyage with 300 invited politician's pals, the Captain realized he didn't dare put the hammer down because hitting a floating tree might hurt the hull, and insufficient rescue capability existed to take off 300 people in the middle of the Lake. The Edmund completed it's dubious career in Charlotte laying at anchor as people who invested in leases at the terminal and the Duty free onboard bar went broke.
As I write this, there are supposedly 5500 cases of untaxed liquor and wine in a bonded warehouse someplace in Rochester. Taxpayers are still paying rent on a Morton building that Toronto calls a ferry terminal, and Rochester's magnificent terminal sits empty costing heavy coin per day. The boat squeezed back down the Seaway to work the Mediterranean after being sold at half price to get rid of it, and Grady Johnson retired to be a Government Ethics Professor at RIT. I dare ya to find the liquor.
You mentioned Wegmans. That little family owned and operated business that had one of two stores across from X tower during the Depression just keeps growing. Average store size today is 12 acres under roof. Most stores now contain the current version of cafeteria the downtown stores had during the Depression, some serve alcohol. wegmans.com will give you a mere glimpse. Sadly the company lost it's history as it passed down through 4 generations. One of the original stores remains on W Main. The chain now reaches South to the DC Swamp & beyond. Wegmans is rated as 1 of the Top 100 companies to work for in the US, and still builds most managers within the company. Wegmans is a tourist destination for people visiting Rochester.
There are a few books about this town, but most won't get published because they aren't written by fat women who claim to know history.
