John M. Donaldson (January 17, 1854 – December 20, 1941) was an American architect and artist born on January 17, 1854, in Stirling, Scotland. Donaldson was principal designer of the successful Detroit-based architectural firm Donaldson and Meier from 1880 onwards. Using only the above description and what you know about the world, "Donaldson and Meier became a success following the year 1880." is definitely correct, incorrect, or inconclusive?
