This is a list of photographs considered the most important in surveys where authoritative sources review the history of the medium not limited by time period, genre, topic, or other specific criteria. These images may be referred to as the most important, most iconic, or most influential—but they are all considered key images in the history of photography.

Alley Oop is a syndicated comic strip created December 5, 1932, by American cartoonist V. T. Hamlin, who wrote and drew the strip through four decades for Newspaper Enterprise Association. Hamlin introduced a cast of colorful characters and his storylines entertained with a combination of adventure, fantasy, and humor. Alley Oop, the strip's title character, is a sturdy citizen in the prehistoric kingdom of Moo. He rides his pet dinosaur Dinny, carries a stone axe, and wears only a fur loincloth. Alley Oop's name was most likely derived from the French phrase allez, hop!. Hamlin said, in a 1960s press release, "Just how I happened to pick the name Alley Oop, I don't remember. It may have been because it is a French term used by tumblers and Oop is really a roughhouse tumbler." The name of Alley's girlfriend, Ooola, was a play on a different French phrase, "Ooo-la-la."

The National Black Justice Coalition (NBJC) is American civil rights organization serving primarily lesbian, gay, bisexual, and transgender (LGBT) people. Since 2003, NBJC has collaborated with national civil rights groups and LGBT organizations, advocating for the unique challenges and needs of the African American LGBT community in the United States.

Bacterial display (or bacteria display or bacterial surface display) is a protein engineering technique used for in vitro protein evolution. Libraries of polypeptides displayed on the surface of bacteria can be screened using flow cytometry or iterative selection procedures (biopanning). This protein engineering technique allows us to link the function of a protein with the gene that encodes it. Bacterial display can be used to find target proteins with desired properties and can be used to make affinity ligands which are cell-specific. This system can be used in many applications including the creation of novel vaccines, the identification of enzyme substrates and finding the affinity of a ligand for its target protein.

This system can be used in many applications including the creation of novel vaccines, the identification of enzyme substrates and finding the affinity of a ligand for its target protein. Bacterial display is often coupled with magnetic-activated cell sorting (MACS) or fluorescence-activated cell sorting (FACS) techniques. Competing methods for protein evolution in vitro are phage display, ribosome display, yeast display, and mRNA display. Bacteriophage display is the most common type of display system used although bacterial display is becoming increasingly popular as technical challenges are overcome. Bacterial display combined with FACS also has the advantage that it is a real-time technique.

Bacterial nanowires (also known as microbial nanowires) are electrically conductive appendages produced by a number of bacteria most notably from (but not exclusive to) the Geobacter and Shewanella genera. Conductive nanowires have also been confirmed in the oxygenic cyanobacterium Synechocystis PCC6803 and a thermophilic, methanogenic coculture consisting of Pelotomaculum thermopropionicum and Methanothermobacter thermoautotrophicus.
