Gottlieb Daimler had suffered from heart problems for some time. In the winter of 1892/93 he fell ill once again, and was sent to Florence to recuperate in the spring. It was there that Daimler met Lina Hartmann née Schwend, whose acquaintance he had once made when visiting friends in Cannstatt. His first wife Emma had died on July 28, 1889, and he was very struck with the worldly, 22 years younger Lina Hartmann. Daimler decided to marry again, and his wedding to Lina Hartmann took place in Schwäbisch Hall on July 8, 1893. Suffering from the effects of his heart complaint, Daimler made a number of mistakes where Daimler-Motoren-Gesellschaft was concerned. For example he declined to acquire a further 102 shares which would have ensured a majority holding, possibly because he may have doubted whether the situation of DMG would improve in the future. The increasingly difficult relationship between Daimler and Lorenz/ Duttenhofer eventually led to them excluding him as a shareholder by insisting on repayment of the 400,000 Marks which Daimler-Motoren-Gesellschaft owed to the bank. Otherwise they threatened to declare the company insolvent, but gave Daimler the option of purchasing his shareholding and the rights to his inventions from him for the sum of 66,666 Marks. To avoid bankruptcy, Daimler agreed. They were rid of him, but this did nothing to improve the company’s fortunes. There was no further technical progress, and the financial situation steadily worsened.
In 1895 Maybach refused an offer of employment from Daimler-Motoren-Gesellschaft, stating that he would not return without Daimler. Duttenhofer would probably never have agreed to this, however something else occurred which brought about a change of mind. By virtue of the Phoenix engine designed by Maybach, Daimler engines became a major talking point abroad. A group of English industrialists, whose spokesman was Frederick R. Simms, wished to purchase the rights to this engine for England – at a price of 350,000 Marks. A condition was attached to this offer, however: Daimler must be allowed to rejoin the company. The return of Daimler and Maybach enormously improved the fortunes of DMG. Daimler received his shareholding of 200,000 Marks back, plus bonus shares to the value of 100,000 Marks. He was appointed to the Supervisory Board as an expert adviser and general inspector. On November 8, 1895 Maybach was appointed Chief Engineer of Daimler-Motoren-Gesellschaft, and was also granted shares to the value of 30,000 Marks. The foremost concern for Maybach was now to restore the competitiveness of DMG with technically advanced and reliable products. The designs developed at the Hermann Hotel provided an important basis for this. Gottlieb Daimler died five years later, on March 6, 1900.
