Who became the first rider to win two TT races in one week in 1925?

Wal Handley became the first rider to win two TT races in one week in 1925.

Handley first won the six-lap Junior TT on a Rex-Acme, averaging 65.02 mph around the Mountain Course. Later in the same race week, he won the four-lap Ultra-Lightweight TT, again riding a Rex-Acme. That second victory established the milestone: no previous TT rider had won two separate races during one week.

The Ultra-Lightweight class was for motorcycles of no more than 175 cc and had been introduced only the year before. Handley’s winning machine averaged 53.45 mph and set a race record, while his lap record stood at 54.12 mph. The 1925 meeting also included Senior, Lightweight and Sidecar races, so the achievement was not two wins in the same class. A nearby fact often causes confusion: Howard Davies won the 1925 Senior TT on an HRD, while Jimmy Simpson set the fastest Senior lap but did not finish.
