Roentgen married Bertha Ludwig in which year?

Roentgen married Bertha Ludwig in which year?

• A. 1865
• B. 1872
• C. 1895
• D. 1901

Answer: (B)

Biographical dates help place a scientist’s life events in context. Wilhelm Conrad Röntgen’s marriage to Bertha Ludwig occurred in 1872, well before his landmark X-ray discovery in 1895. Knowing his birth year (1845) makes this marriage year fit his life timeline—he was about 27 at the time. The other years don’t match the marriage event, reinforcing why 1872 is the correct year.
