Invented The Multiple Wave Oscillator (1923) — spark gap transmitter with concentric rings forming electrical dipole antennas emitting a vast harmonic band (per the engineering record, broad-band coverage with documented effects from RF through GHz ranges).
Documented cancer remissions 1925–1942 form the historical baseline for wide-band harmonic entrainment therapy. The mainstream-medicine response was the same the academy's dismiss-without-checking pattern applied to Rife: dismissal as 'quackery' without rigorous replication of the specific broadcast parameters. The mechanism — entraining cellular cell-voltage oscillation back to healthy reference — anticipates Levin's modern cell-voltage morphogenesis work by ~80 years.
