What did Reginald Fessenden invent?

  1. The first cardiac pacemaker

  2. The telephone

  3. The radio

  4. The snowmobile

The correct answer is: The radio

Reginald Fessenden is known for his role in developing the first working radio transmitter, which laid the foundation for modern radio technology. He did not invent the cardiac pacemaker (that was Wilson Greatbatch), the telephone (Alexander Graham Bell), or the snowmobile (Joseph-Armand Bombardier). He was also involved in the development of other technologies such as sonar and wireless telephony, but his most significant contribution was in the field of radio.
