Incorrect file info

Paste it to Notepad and save as "Author and Copyright.jsx" (incl. double quotes) in Adobe Startup Scripts folder, so 'C:\Program Files\Common Files\Adobe\Startup Scripts CC\Adobe Bridge CC 2018', and then reopen Bridge. Right click on the folders containing (subfolder with) images where (some) have written Author and Copyright fields and select last item from the commands list: "Author and Copyright". This functionallity will be always available in your Bridge as far as you keep the 'Author and Copyright.jsx' script in mentioned folder.

If the 'Author and Copyright' item won't be at its place then go to Edit/Preferences/StartupScripts. Then find checkbox with item name and check it. Reopen Bridge and script should be loaded.

#target bridge
NtC = new MenuElement('command', 'Author and Copyright', 'at the end of Thumbnail')
NtC.onSelect = function() {
     function rec(sF, dst, i) {
          if (fld = io(sF)) sF = sF.getFiles(); for(; i < sF.length; i++) {
               if (io(fof = sF)) dst.push(fof.name), rec(fof, dst, 0)
               else if((r = /.jpe?g$/i).test(fof)) {
                    (md = new Thumbnail(fof).synchronousMetadata)
                    .namespace = 'http://ns.adobe.com/photoshop/1.0/'
                    md.Author = '', md.Copyright = ''
               }
          }
          return dst
     }
     function io(v) {return v instanceof Folder}
     if (len = (sel = (ad = app.document).selections).length) {
          for(h = 0; h < len; h++) if (io(spec = sel.spec)) rec(spec, [], 0)
     }
}

I discovered that the previous owner of the D810 had set the copyright and author in the camera. I fixed that issue. Now I am hunting for a fast way to correct all the photos in Bridge. If I go into a folder and select all photos and try to change the data in mass I find I can't type any characters into the Author and Copyright fields.

That would probably be the person who originally created them and therefore holds the copyright -

I would think that would be easy to do using the bridge select all the file then edit their metadata bridge should change all the selected files metadata to what you edited.
