In a recent comment - aawillsher asked the following question:
"I was recently wondering about a related question — what is the most HR’s hit by a player (season or career) who never hit more than one in a game?"
Using an obscure feature of the PI Batting Streak finder, we can attempt to answer this question.
Step 1: On the bottom right corner select "Choose additional, advanced criteria:" and set HR>=1. This limits our pool to games in which a player has homered.
Step 2: On the top right set HR=1.
Step 3: For a single season check the box "to start a season"
We may have to manually remove some results if a player had his first multiple home run game late in a year.
Here are the results (1956-2008) to start a single season:

Aaron snapped his streak with a 2 HR game on September 10th. The other players all hit 35 or more home runs without hitting 2 or more in one game.
To figure out the career leader involves a little more work. (You can't simply check off to start a career because the PI limits the search to the players first 400 games) However, we can do the same search as before and not limit it to the beginning of a season.
This yields the following result.

Rusty Staub had the longest streak (1956-2008) of home run games with just one. However, Staub did have 12 multiple homerun games in his career. Marquis Grissom's first 109 home runs were all hit in different games. However, after that he had 9 multiple homerun games. Similary, the streaks of Ripken and Yastrzremski were oddities in careers full of mutiple home run games. This leaves Lou Pinella as the only player (1956-2008) to have hit more than 100 career home runs, but never 2 in the same game.
